Question

11. A grocer sold rice at Rs. 48 per kg by mixing 50/50 kg price purchasing at Rs. 40 and Rs.
50 respectively. Find the profit or loss percent.​

Answer 1

Answer:

20 / 3 % or 6.667 %

Step-by-step explanation:

S.P of 1 kg = Rs 48

C.P of 1 kg = Rs 40

C.P of 50 kg = Rs 40 * Rs 50

                     = Rs 2000

C.P of 1 kg = Rs 50

C.P of 50 kg = Rs 50 * 50

                     = Rs 2500

Now,

Total C.P of 100 kg rice = Rs 2000 + Rs 2500

                                       = Rs 4500

Again,

S.P of 1 kg rice = Rs 48

S.P of 100 kg rice = Rs 48 * 100

                             = Rs 4800

Here,

S.P > C.P

P = S.P - C.P

  = Rs 4800 - Rs 4500

  = Rs 300

So,

P% = P / C.P * 100%

     = Rs 300 / Rs 4500 * 100%

     = Rs 20 / 3 %

     = Rs 6.667 %
