Question

two number are in the ratio 8:9 if the sum of the number is 153,find the number

Answer 1

8u + 9u = 17u

17u = 153

1u = 153 / 17 = 9

8u = 9 x 8 = 72

9u = 9 x 9 = 81

The numbers are 72 and 81 respectively.

Answer 2

The numbers are 72 and 81

Given : Two numbers are are in the ratio 8:9 if the sum of the number is 153

To find : The numbers.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the two numbers)

Let, the two numbers = 8x and 9x

(obtained from the ratio 8:9)

The sum of the two numbers :

= 8x + 9x

= 17x

According to the data mentioned in the question

17x = 153

x = 153/17

x = 9

The first number = 8x = 8 × 9 = 72

The second number = 9x = 9 × 9 = 81

Hence, the numbers are 72 and 81
