Answer:

2)400

Step-by-step explanation:

1) 20%of 120=24

so, 120+24=144

2) 20%of 500=100

500-20%=400

Answer 2

Answer:

Ans. 1 First monthly consumption=120 litres.

Percent increase=20%.

20% of 120 =20/100*120=24 litres.

120+24= 144 litres.

Ans. 2 Cost of saree=500

Discount by shopkeeper=20%

New cost of saree = 20%of 500

20% of 500 = 100

So discount amount = Rs.100

New cost of saree = Rs.400.
