Question

on seeling a mobile for 4500 a shopkeeper losses 10%.for what amount he should sell it to gain 15%

Answer 1

Step-by-step explanation:

CP = ?

SP = 4500

Loss = CP - 4500

Loss % = 10%

CP. - SP / CP × 100 = 10

CP - 4500/CP × 100 = 10

CP - 4500 /CP = 1/10

10CP - 45000 = CP

9CP = 45000

CP = 45000/9 = 5000

SP - 5000/5000 ×100 = 15

SP - 5000/50 = 15

SP - 5000 = 15×50

SP - 5000 = 750

SP = 5000+750 = 5750
