Question

Q1: Aryan sold a mobile phone for Rs.2500 which
he had bought for Rs.2250 . Find profit or loss he got ?
Q2: a fruit -seller buy 16 apples at a rate of Rs .10 per apple and sells 12 of them at Rs.12 per apple . Find his profit or loss .

Answer 1

1) CP= Rs 2250 , SP = Rs 2500
Profit = SP - CP = 250 Rs
2) total money spent on the apples bought (CP)= number of apples x Rs = 16 x 10= 160 rs
total money earned by the apples sold (SP) = number of apples x Rs = 12 x 12 = 144Rs
Loss = CP - SP = 160 - 144 = 16 Rs

Answer 2

1)Here S.P is greater than C.P. so he will get profit
   Profit=S.P.-C.P
 ⇒2500-2250=Rs.250
  so,Aryan has a profit of Rs 250.
2)Given C.P. of 1 apple is Rs.10
   Then, 
   C.P. of 16 apples=16×10=Rs.160
   Again,he sells each apple @Rs.12
   ⇒S.P. of 12 apples=12×12=Rs.144
   Here,C.P. is greater than S.P so his loss=C.P.-S.P.=160-144=Rs.16
