Question

Pls do this question no 8

Answer 1

(i)

Given that a vendor bought 120 sweets at 20p each.

Total cost price = 120 * 20

                          = 2400.

(ii)

Given that 18 were consumed = (120 - 18) = 102.

He sold the remaining at 30 p each.

Total Selling price = 102 * 30

                              = 3060.

Here, Selling price > Cost price. So, Gain has occurred.

(iii)

We know that Gain = Selling price - Cost price

                                 = 3060 - 2400

                                 = 660.

We know that Gain% = [Gain * 100]/CP

                                   = (660 * 100)/2400

                                   = 66000/2400

                                   = 27.5%.

Therefore, Profit % = 27.5%.

Hope it helps!

Answer 2

Here,

No. of sweets = 120

Rate = 20 p each

So,

C.P = 120 x 20 /100 = Rs. 24

since 18 sweets are consumed ,

So

Now no of sweets = 120 - 18 = 102

Rate = 30 p each

So,

S.P = 102 x 30 /100 = Rs. 30.6

• Since S.P > C.P

So

Gain = S.P - C.P

        = 30.6 - 24 = Rs. 6.6

• Gain % = Gain /C.P x 100 %

                   = 6.6 /24 x 100  = 27.5 %
