Question

(find the cost of total rice) A merchant mixes two variety of rice one costing ₹ 35 per kg and another at ₹ 45 per kg in the ratio 3 : 2​

Answer 1

Answer:

Let quantity of one type of rice

= 3x

Let quantity of other type of rice be 2x

Then,

Total Cost price of rice CP

= 3x*35 + 2x*45

= 105x + 90x

= 195x

Selling price of rice

= 5x*41.60

= 208x

Therefore,

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

=[(208x - 195x)/195x]*100

= 1300/195

= 6.6 %

Answer 2

Answer:

Let quantity of one type of rice

= 3x

Let quantity of other type of rice be 2x

Then,

Total Cost price of rice CP

= 3x*35 + 2x*45

= 105x + 90x

= 195x

Selling price of rice

= 5x*41.60

= 208x

Therefore,

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

=[(208x - 195x)/195x]*100

= 1300/195

= 6.6 %
