Options
- Rs. 24
- Rs. 25
- Rs. 26
- Rs. 27

CORRECT ANSWER : Rs. 25

Discussion Board
Cost of a mango

m+o=35
let cp of mangoes=m
let cp of oranges=o
selling price=cp(1+p%/100)
So,Selling price of mangoes=m(1+20/100)=6m/5
So,Selling price of oranges=o(1-10/100)=9o/10
Given profit=4
Total SP-Total CP=4
6m/5+9o/10-(m+o)=4
6m/5+9o/10=39(since m+o=35)------>equation 1
m+o=35------>equation 2
On solving two equations
Mangoes Cost=25
Oranges Cost=10
