Question

The ratio of the present ages of Pandeyji and Chutki is 5 : 8. After 8 years, the ratio of their ages will be 7 : 10, find the ratio of their ages after 12 years
plz answer correctly​

Answer 1

Answer:

P's present age = 8x years

Q's present age = 5x years

After 4 years,

8x+45x+4=43

=> 24x + 12 = 20x + 16

=> 4x = 4 => x = 1

P's age 7 years hence = 8x + 7 = 8 + 7 = 15 years

Required ratio = 15 : 5 = 3 : 1

Age of P = 5x =5×1 =5years.

Age of Q = 8x =8×1=8years.

Answer 2

Step-by-step explanation:

p=(5/8)q

(p+4)=2/3(q+4)

Distribute

p+4-2/3(q)+2/3(4)

Do math

p+4=2/3(q)+8/3

Substitute (5/8)q for p

(5/8)q+4-2/3(q)+8/3

Subtract 5/8(q) from both sides, subtract 8/3 from both sides

4-8/3-2/3(q)-5/8(q)

Find LCDs of fractions

12/3-8/3-16/24q-15/24q

Combine like termsFind LCDs of fractions

12/3-8/3-16/24q-15/24q

Combine like terms

4/3-1/24(q)

Multiply both sides by 24

96/3=q

Reduce fraction

q=32

Substitute 32 for q

p=5/8(32)

Do math

p=20
