Question

By selling a mobile phone at Rs.4500, a man
loses 1/10 th of its cost price. At what price should
he sell it to make a profit of 10%?

Answer 1

Step-by-step explanation:

selling price = 4500₹

loss = 1/10

we can write 1/10 as = 10% loss

always take CP as 100%

10% loss ,so remaining is 90% = SP

90 = 4500

CP. 100 = X

APPLY CROSS MULTIPLICATION METHOD,

X = 5000₹ is CP

At what price should he sell it to make a profit of 10%

100 = 5000

110 = X

APPLY CROSS MULTIPLICATION METHOD,

X = 5500₹ is SP for to get 10% profit
