Question

The difference between the ages of somu and priya is 10 years and their ratio between their ratio between their ages is 3:1 .what is the sum of their ages 4 years ago

Answer 1

Let the ages of some and Priya be x and y

a/q. x-y=10..................(1)

now x/y=3/1

so, x=3y........(2)

now putting the value of x in equation

1

So,3y-y=10

=2y=10

=y=10/2

y=5

Now x-y=10

=x-5=10

=x=10+5

=So,x=15

Answer 2

Answer: 12

Step-by-step explanation:

This is sum is solved by ratio method.

Difference is 10 years.

so the Difference ratio of 3:1 ==>2

2==10;

1==05;

so, the 3:1 become 15:05

Question is 4 years ago, we reduce the ratio 11:01

Sum of the ages is 11+01=12
