**5)The price of commodity X increases by 40 paise every year, while the price of commodity Y increases by 15 paise every year. If in 2001, the price of commodity X was Rs. 4.20 and that of Y was Rs. 6.30, in which year commodity X will cost 40 paise more than the commodity Y? **

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.

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%
