Answer: (a)

Let us consider a packet or rice marked 1kg. It's actual weight is 80% of 1000 gm = 800 gm

Let C.P. of each gm be Rs.1.

Then, C.P. of this packet = Rs. 800

S.P. of this packet = 110% of C.P. of 1kg

= $110/100 × 1000$ = Rs.1110

∴ Gain % = $(1100 - 800)/1100 × 100$ = 37.5%

Answer: (d)

Let the cost price of radio be Rs. 1000.

Dealer sold it at a loss of 2.5%

i.e. selling price = 997.5

When he sold it Rs. 100 more, then selling price = 1007.5

(gain = 7$1/2$ %)

Now, In order to gain 12$1/2$ %,

Selling price will be 1000 × $25/200 + 1000$ = 1125.

Answer: (d)

Cost price of bicycle = Rs. 5,200.

∴ Loss = 6000 - 5500 = 500

Hence, loss % = $500/6000 × 100$ = 8.33%
