______________________________

(a)
6% more than 120
= 120 + 6% of 120

100% ---- 120
6% ------- ? ( say x)

Cross Multiply

120× 6 = 100x
=> x = 720/100
=> x = 36/5
=> x = 7.2

Therefore,

6% more than 120
= 120 + 7.2
= 127.2

The amount 6% more than Rs 120 = 127.2

(b)
15% less than 400
= 400 - 15% of 400

100% ---- 400
15% ------- ? (say x)

Cross Multiply

100×x = 400× 15
=> x = 15×4
=> x = 60

Therefore,

15% less than 400
= 400 - 60
= 340

The amount 15% less than Rs.400 = Rs. 340
