Question

Two number are such that the ratio between them is 3 : 5. If each increased by 10, the ratio between the new number so formed is 5 : 7. find the original number​

Answer 1

Answer:

Let the ratio,3:5 be taken as 3x and 5x

BTP,

If the ratios are increased by 10 i.e,

3x+10 and 5x+10

3x+10+5x+10=5x+7x

8x+20=12x

8x-12x=-20

-4x=-20

x=-20/-4

=5

Therefore,the original ratio 3x and 5x

3x=3×5=15

5x=5×5=25
