And had profit of 12%. Find the cost price of each mobile

Answer 1

Answer:

hope it help u..

Step-by-step explanation:

selling price of 5 mobiles is Rs 35,840

show the selling price of 1 mobile is Rs 35840/5

= Rs 7168 (SP)

now according to formula p%=P/CP*100

SO P=(p%*CP)/100 ...... equation 1

now we also know that P= SP - CP

SO now put the value of p from equation 1

so

(p%*CP)/100= SP - CP

12*CP=100 (7168-CP)

12CP= 716800 - 100CP

12CP+100CP= 716800

112CP= 716800

CP= 6400
