Question

Mohan spent 1/3 of his money to buy a book and 1/2 of the rest fona copy and he had remained RS.36 .Then how much money has he taken?​

Answer 1

Answer:

Rs 108

Step-by-step explanation:

let the money he has taken = x

he spent 1/3rd to buy a book = x×1/3

he spent 1/2nd of the rest on fone copy =

(x-x×1/3)1/2

= x(2/3)1/2

= x/3

acc. to question,,

he had remained Rs36

so,, (x-x/3-x/3) = 36

x(1-1/3-1/3) = 36

x(2/3-1/3) = 36

x(1/3) = 36

x = 36×3

x = 108

x = Rs 108 ....ans.
