Question

The L.C.M. of two numbers is 196. The numbers are in the ratio 4:7. The sum of the numbers is: ( A ) 32 ( B ) 77 ( C ) 86 ( D ) 28

Answer 1

Answer:

(B)

Step-by-step explanation:

Since the numbers are in 4:7 ratio

so we can consider one number to be 4x and other 7x

sum of these numbers is 11x

As we know

If you multiply any 1 digit integer with 11 it gives repetition of that number

In our case the number is 7

Hence it is giving 77

By this we will get our numbers which will be 28 and 49

Whose LCM if we take we will get 196

Remember these kind of questions does not have one proper method to solve them, we have to do hit and trial with our options.

Have a nice day.
