Question

The LCM of Samved & Prutha's age is 40 & the ratio of their ages is 2:5. What is the sum of their ages?
1. 12 yrs
2. 27 yrs
3. 35 yrs
4. 28 yrs
​

Answer 1

$\:$The sum of their ages is 48 years.

Given, the LCM of Samved and Pruthas' age is 40. Let us assume the common ratio to be 'x'. LCM of 2x and 5x is 10x, as for 2 and 5 it is 10. So, sum of their ages = (8+40) years = 48 years.

Answer 2

Answer:

28 years

Step-by-step explanation:

Samved: Prutha = 2:5 and L.C.M of their ages is 40. So. 5x Samved's age= 40 = 2 x Prutha's age.

.. Samved's age: = 40 +5=8 years

Prutha's age =40÷2= 20 years

Their total age is 8 + 20 = 28 years. Hence, the answer choice is (4).
