Question

Nidhi is 5 years old. her mother is 29 years old and her grandmother is 54 years old .

In how many years will the sum of their ages be equal to 100 years ?
​

Answer 1

Answer:

Step-by-step explanation:

In 4 years the sum of their ages will be 100.

Solution: sum of current ages=5+29+54=88 which is 12 less than 100.

So lets divide 12 by 3=4

So after four years their age will be (5+4)+(29+4)+(54+4)=100.

Answer 2

Answer: It will take only 4 years to make the sum of their ages equal to 100.

Step-by-step explanation:

1. First, you have to add all the initial ages.

5 + 29 + 54 = 88

2. Since they're asking how many years the ages will become 100, you have to subtract 88 from 100.

100 - 88 = 12

3. Now, divide 12 by the number of people (3 people are there, Nidhi, her mother, and her grandmother)

12 ÷ 3 = 4

Thus, the answer is 4.
