Question

A shopkeeper mixea 2 tyoes of rice in ratio 3:2. If cp of 1st rice is 35/kg and of other 45/kg find %p when sold at 41.60/kg

Answer 1

Answer:

6.6 %

Step-by-step explanation:

Let quantity of one type of rice= 3a

Let quantity of other type of rice be 2a

Then,

Total Cost price of rice CP = (3a x 35) + (2a × 45)

= (105a + 90a)

= 195a

Selling price of rice

= 5a x 41.60

= 208a

Therefore,

Gain % = [(SP - CP) / CP]*100

=[(208a - 195a)/195a]×100

= 1300/195

= 6.6 %
