Question

The ages of Sonal and Manoj are in the ratio 7:5. Ten years hence, the ratio of their ages
will be 9:7. Find their present ages.
the one who answers this clearly will be marked brilientiest

Answer 1

Step-by-step explanation:

Given:-

The ratio of Present ages of Sonal and Manoj = 7:5

To Find:-

Present ages of Sonal and Manoj after 10 Years

Solution:-

Let the age of Sonal be 7x years and age of Manoj be 5x years

10 years later their age will (7x+10) and (5x+10)

Given ratio of ages after 10 years=9:7

So now assume the ages be 9x and 7x

∴7x+10+5x+10=9x+7x

9x−5x=20

4x=20

x=5

So, the present age of Sonal=7x=7×5=35years

and the present age of Sonal=5x=5×5=25years

Final Answer:-

Therefore the present ages of Sonal and Manoj are

35 and 25 years

Answer 2

Answer:

Solution-

Solution-Ratio of the present ages of Sonal and Manoj are 7:5

Solution-Ratio of the present ages of Sonal and Manoj are 7:5Let us assume, present age of Sonal is 7x years and present age of Manoj is 5x years, where x is the multiplier

Solution-Ratio of the present ages of Sonal and Manoj are 7:5Let us assume, present age of Sonal is 7x years and present age of Manoj is 5x years, where x is the multiplier10 years hence,

Solution-Ratio of the present ages of Sonal and Manoj are 7:5Let us assume, present age of Sonal is 7x years and present age of Manoj is 5x years, where x is the multiplier10 years hence,Sonal's age is 7x + 10 and Manoj's age is 5x + 10

Solution-Ratio of the present ages of Sonal and Manoj are 7:5Let us assume, present age of Sonal is 7x years and present age of Manoj is 5x years, where x is the multiplier10 years hence,Sonal's age is 7x + 10 and Manoj's age is 5x + 10Therefore, ratio of their age = 7x+10 : 5x+10

Solution-Ratio of the present ages of Sonal and Manoj are 7:5Let us assume, present age of Sonal is 7x years and present age of Manoj is 5x years, where x is the multiplier10 years hence,Sonal's age is 7x + 10 and Manoj's age is 5x + 10Therefore, ratio of their age = 7x+10 : 5x+10Given:

Solution-Ratio of the present ages of Sonal and Manoj are 7:5Let us assume, present age of Sonal is 7x years and present age of Manoj is 5x years, where x is the multiplier10 years hence,Sonal's age is 7x + 10 and Manoj's age is 5x + 10Therefore, ratio of their age = 7x+10 : 5x+10Given:7x+10 : 5x+10 = 9:7(7x+10) / (5x+10) = 9/7

Solution-Ratio of the present ages of Sonal and Manoj are 7:5Let us assume, present age of Sonal is 7x years and present age of Manoj is 5x years, where x is the multiplier10 years hence,Sonal's age is 7x + 10 and Manoj's age is 5x + 10Therefore, ratio of their age = 7x+10 : 5x+10Given:7x+10 : 5x+10 = 9:7(7x+10) / (5x+10) = 9/77(7x+10) = 9 (5x+10)

Solution-Ratio of the present ages of Sonal and Manoj are 7:5Let us assume, present age of Sonal is 7x years and present age of Manoj is 5x years, where x is the multiplier10 years hence,Sonal's age is 7x + 10 and Manoj's age is 5x + 10Therefore, ratio of their age = 7x+10 : 5x+10Given:7x+10 : 5x+10 = 9:7(7x+10) / (5x+10) = 9/77(7x+10) = 9 (5x+10)49x + 70 = 45x + 90

Solution-Ratio of the present ages of Sonal and Manoj are 7:5Let us assume, present age of Sonal is 7x years and present age of Manoj is 5x years, where x is the multiplier10 years hence,Sonal's age is 7x + 10 and Manoj's age is 5x + 10Therefore, ratio of their age = 7x+10 : 5x+10Given:7x+10 : 5x+10 = 9:7(7x+10) / (5x+10) = 9/77(7x+10) = 9 (5x+10)49x + 70 = 45x + 904x = 20

Solution-Ratio of the present ages of Sonal and Manoj are 7:5Let us assume, present age of Sonal is 7x years and present age of Manoj is 5x years, where x is the multiplier10 years hence,Sonal's age is 7x + 10 and Manoj's age is 5x + 10Therefore, ratio of their age = 7x+10 : 5x+10Given:7x+10 : 5x+10 = 9:7(7x+10) / (5x+10) = 9/77(7x+10) = 9 (5x+10)49x + 70 = 45x + 904x = 20x = 5

Solution-Ratio of the present ages of Sonal and Manoj are 7:5Let us assume, present age of Sonal is 7x years and present age of Manoj is 5x years, where x is the multiplier10 years hence,Sonal's age is 7x + 10 and Manoj's age is 5x + 10Therefore, ratio of their age = 7x+10 : 5x+10Given:7x+10 : 5x+10 = 9:7(7x+10) / (5x+10) = 9/77(7x+10) = 9 (5x+10)49x + 70 = 45x + 904x = 20x = 5Therefore, present age of Sonal = 7x = 7 * 5 = 35 years

Solution-Ratio of the present ages of Sonal and Manoj are 7:5Let us assume, present age of Sonal is 7x years and present age of Manoj is 5x years, where x is the multiplier10 years hence,Sonal's age is 7x + 10 and Manoj's age is 5x + 10Therefore, ratio of their age = 7x+10 : 5x+10Given:7x+10 : 5x+10 = 9:7(7x+10) / (5x+10) = 9/77(7x+10) = 9 (5x+10)49x + 70 = 45x + 904x = 20x = 5Therefore, present age of Sonal = 7x = 7 * 5 = 35 years and present age of Manoj = 5x = 5 * 5 = 25 years
