Question

by mixing two brands of tea and selling the mixture at the rate of RS.177 per kg , a shopkeeper makes a profit of 18% . if to every 2 kg of one brand costing RS.200 perkg, 3 kg of the other brand is added ,then how much perkg should other brand cost?​

Answer 1

SP = 177

18 % profit

CP = 150

1st method

$150 = \frac{2 \times 200 + 3 \times x}{2 + 3}$

350 = 3x

x = 116.66

2 nd method

brand 1. brand 2

200. x

150

2. 3

$( \frac{200 - 150}{150 - x} ) = \frac{3}{2}$

Answer : Rs. 116.66
