Q12 Two numbers are in the ratio 8:7
Their sum is 60 find the numbers-​

Answer 1

⛦ Given :

• Two numbers are in ratio 8 : 7
• Sum of these two numbers is 60.

⛦ To find :

• The numbers.

⛦ Solution :

• Let the first number be 8x

• And the second number be 7x

According to Question,

→ Sum of two numbers = 60

↬ 8x + 7x = 60

↬ 15x = 60

↬ x = 60/15

↬ x = 4

Therefore,

• The first number (8x) = 8×4 = 32
• The second number (7x) = 7×4 = 28

Check :

As it is given that the ,

Sum of two numbers = 60

Thus,

→ 32 + 28 = 60

→ 60 = 60

Hence, L.H.S. = R.H.S.

Thus, Checked !

Answer 2

Question :-

Given :-

• The ratio of two numbers is 8:7
• The sum of the numbers is 60

To Find :-

• What are the Numbers ?

Solution :-

Let the First number be 8x

Let the Second Number be 7x

According to the Question :-

⇛ Ratio + Ratio = Sum of Numbers

⇛ 8x + 7x = 60

⇛ 15x = 60

⇛ x = 60/15

⇛ x = 4

━━━━━━━━━━

First Number = 8x = 8 × 4 = 32

Second Number = 7x = 7 × 4 = 28
