Answer 2

Answer:

Prateeksha pay for the necklace is 2345.2

Step-by-step explanation:

Kajol buys a necklace for ₹2200 and sells it to Meera at 4%

so, Meera pay more 4% of ₹2200

so, to find 4% more

find 1% of ₹2200

to find 2200/100

1% of ₹2200 is ₹22

for 4% multiply 22 by 4

so Meera pays to kajol is ₹2288

Meera sells it to Prateeksha at 2.5% profit

So, 2.5% of 2288

so 0.1% of 2288 is 2288/1000

so 0.1% of 2288 is 2.288

multiply 2.288 by 25

so 2.5 of 2288 is 57.2

Prateeksha pay for the necklace is 2288 + 57.2

= 2345.2
