Question

Rajveer was not paying attention in the class, so instead of multiplying a number M by 2/7 he divided M by 2/7. Rajveer's value was 27/14 more than the expected value of M. What is M?​

Answer 1

As per question :-

M÷2/7-27/14=M*2/7

7M/2-27/14=2M/7

7M/2-2M/7=27/14

45M/14=27/14

45M=27

M=27/45

M=3/5
