Question

A grocer purchase 150kg of rice at Rs25 per kg. he sells 70 kg at a profit of5%. at what profit percent should he sell the remaining 80kg so as to make an overall profit of 15%​

Answer 1

Answer:

23.75%

Step-by-step explanation:

Original cost = 25*150 = 3750Rs

To have a 15% profit, the selling price should be (115/100)*3750 =4312.5Rs

If 70 kg is sold at 5%, Let 80 kg be sold at x%

Here we get the following equation:

(70)*(25)*(105/100) + (80)*(25)*(x/100) = 4312.5

=> 1837.5 + (80)*(25)*(x/100) = 4312.5

=>20x = 2475

=> x = 123.75

Subtracting 100,

Profit% = 23.75%

Hope it helps!
