Question

two no are in ratio 3:5 when 5 is added to new ratio is 7:11 find the no

Answer 1

Answer:

Let the rational between two numbers be x

As per the statement, two numbers are in the ratio of 3: 5.

Hence the numbers are 3x and 5x. Their ratio

3x / 5x = 3 / 5

but when they are increased by 10, their ratio is 5 : 7.

After increase, the numbers will be 3x + 10 and 5x + 10. Their ratio

(3x+10) / (5x+10) = 5 / 7

Cross multiplication

5 (5x + 10) = 7 (3x + 10)

25x + 50 = 21x + 70

25x - 21x = 70 - 50

4x = 20

x = 20 / 4

x = 5

The rational is 5. Hence the numbers

One number = 3x = 3 × 5= 15

Other number = 5x = 5 × 5 = 25

Hence the numbers are 15 and 25
