Question

a dishonest shopkeeper professes to sell sugar at its cost price but uses a weight of 980g for 1kg.find his profit percent.

Answer 1

Let the c. P of 1 gram of pulses be Rs.1

C. P of 950 grams =RS. 950

S. P of 950 grams= C. P of 1 kg =RS. 1000

Gain =S. P - C. P=Rs.1000 - 950= RS. 50

Hence gain %= 50*100 /950= 5 five by nine percent
