Validate

Solution:

Let the salary of Mr. John be Rs. x; then
Expenditure on food and education

= {24+ 15}/ 100× x

= \Rs. 39/ 100 x

Remaining salary

= x- 39/ 100x = \Rs. 61/ 100 x

Expenditure on entertainment and conveyance

={25+20}/100×61/100x

=\Rs 549/2000x

Now,

61/100x-549/2000x=10736

⇒x=\Rs. 32,000
