Question

Rs 160 Frankie's were sold how many sandwiches should be sold

Answer 1

Answer:

S.P of one pen = Rs. 160/90

Let C.P of one pen be Rs. x

So, 20 % loss means :

(80/100) * x = 160/90

Therefore, x = Rs. 20/9

For 20 % profit, the S.P of one pen should be,

(120/100) * (20/9) = 24/9

For Rs. 96,

96 / (20/9) = 96/24 * 9 = 36 Pens.

Note : 20 % loss means,

C.P - 20/100 * C.P

=> (100–20)/100 * C.P

=> 80/100 * C.P

Similarly, 20 % profit means,

C.P + 20/100 * CP

=> (100+20)/100 * C.P

=> 120/100 * C.P
