Question

a vendor sells apple at 10 for rs. 1 gaining 40%. how many apple did he buy for rs1 ?​

Answer 1

Step-by-step explanation:

S.P of 10 apples =1

S.P of 1 apple =1/10

profit 40% so, relation between SP and CP

S.P =1.4* cp

C.P = 1/(1.4*10)=1/14

no of apples he bought for rs 1 =1/cp of 1 apple

= 1/(1/14)

=14 apple
