Arun bought toffees at 6 for a rupee. How many for a rupee he should sell to gain 20%?
A. 2
B. 3
C. 4
D. 5
Answer: Option D
Solution (By Examveda Team)
CP for one toffee = $$\frac{{100}}{6}$$SP will be 20% above the CP.
So,
SP for one toffee = $$\frac{{100}}{6} \times 1.2 = \frac{{100}}{5} = 20$$
Thus, He should sell 5 toffee for Rs. 1 (100 paise)
This Question Belongs to Arithmetic Ability >> Profit And Loss
cp of 6 toffees = rs 1
cp of 1 toffee =rs 1/6
sp of 1 toffee should be=1/6 + 20%(1/6)
=1/6 + 1/30 =1/5
sp of 1 toffee is =1/5
sp of 5 toffee is =1/5*5=1
