Question

Heera bought 25kg of rice at RS 48 per kg and 35kg of rice at RS 60 per kg. He sold the mixture at RS 66 per kg. Find his gain percent.​

Answer 1

C.P OF (Rs48) = 25×48

= 1200

C.P OF (Rs60)= 35×60

= 2100

Total C.P = 1200+2100

= 3300

Total amount of rice= 25+35 = 60kg

S.P = 60 × 66

= 3960

$profit\% \: = \frac{(3960 - 3300) \times 100}{3300}$

profit = 20%

Answer 2

Answer:

C.P OF (Rs48) = 25×48

= 1200

C.P OF (Rs60)= 35×60

= 2100

Total C.P = 1200+2100

= 3300

Total amount of rice= 25+35 = 60kg

S.P = 60 × 66

= 3960

profit\% \: = \frac{(3960 - 3300) \times 100}{3300}profit%=

3300

(3960−3300)×100

profit = 20%
