A. 2010

B. 2011

C. 2012

D. 2013

**Ans.- B **

**Solution :
Suppose commodity X will cost 40 paise more than Y after z years.
Then, (4.20 + 0.40z) - (6.30 + 0.15z) = 0.40
=> 0.25z = 0.40 + 2.10
=> z =2.50/0.25= 250/25 = 10.
=> X will cost 40 paise more than Y 10 years after 2001 i.e., 2011. **

**6) Alfred buys an old scooter for Rs. 4700 and spends Rs. 800 on its repairs. If he sells the scooter for Rs. 5800, his gain percent is: **

A. 4 4/7%

B. 5 5/11%

C. 10%

D. 12%

**Ans.- B **

**Solution:**

Cost Price (C.P.) = Rs. (4700 + 800) = Rs. 5500.

Selling Price (S.P.) = Rs. 5800.

Gain = (S.P.) - (C.P.) = Rs.(5800 - 5500) = Rs. 300.

Gain % =300/5500x 100%= 5 5/11%

Cost Price (C.P.) = Rs. (4700 + 800) = Rs. 5500.

Selling Price (S.P.) = Rs. 5800.

Gain = (S.P.) - (C.P.) = Rs.(5800 - 5500) = Rs. 300.

Gain % =300/5500x 100%= 5 5/11%

**7) Samant bought a microwave oven and paid 10 % less than the original price. He sold it with 30% profit on the price he had paid.What percentage of profit did Samant earn on the original price? **

A. 17%

B. 20%

C. 27%

D. 32%

**Ans.- A **

**Solution:**

Let the original price=Rs.100.

Then, C.P= Rs.90.

S.P =130% of Rs. 90=Rs.(130/100×90)= Rs.117.

Required percentage= (117 - 100)%=17%.

Let the original price=Rs.100.

Then, C.P= Rs.90.

S.P =130% of Rs. 90=Rs.(130/100×90)= Rs.117.

Required percentage= (117 - 100)%=17%.

**Solution:**

C.P = RS.67 , S.P = Rs.70 As, S.P >C.P it means profit .profit = S.P-C.P = Rs.3

C.P = RS.67 , S.P = Rs.70 As, S.P >C.P it means profit .profit = S.P-C.P = Rs.3

**9)The owner of an electronics shop charges his customer 22% more than the cost price. If a customer paid Rs 10,980 for a DVD player, then what was the cost price of the DVD player? **

CP of DVD player = Rs x

According to the question,

= x(1+22/100)

= Rs 10980

x = 10980 × 50/61 = Rs 9000

CP of DVD player = Rs x

According to the question,

= x(1+22/100)

= Rs 10980

x = 10980 × 50/61 = Rs 9000
