Question

Mahesh earned a profit of 5% by selling a washing machine for Rs 7140 find the cost price of the washing machine my

Answer 1

Answer:

6800

Step-by-step explanation:

cp = sp * 100/ (100 + profit%)

cp = cost price, sp= selling price

cp = 7140* 100/(100+5)

cp = 7140 * 100/105

cp = 68 * 100 = 6800

so cost price is 6800

to verify profit is 5% means 6800*5/100= 340

then sp = cp + profit

sp = 6800+ 340 = 7140
