D

Let the list price be x

So the discount offered by the retailer is 0.1x

and the SP becomes 0.9x

Since SP given is 108, equating we get

0.9x = 108

x =120

Since the wholesaler gives 20% discount on the list price, it means he sells the product at 80% of the list price which is

80% of 120 = 96

This becomes CP for the retailer

So Profit earned by the retailer is 108 – 96 = Rs. 12

Hence, option D is correct..

C

Lets first calculate the total rate % that Aditya will have after 3 years:

As per the question Aditya invested at rate of 12% pa simple interst

So, for 3 years tenure he will get = 12 × 3 = 36%

And the amount that Bhushan invested at rate of 10% pa compound interest

By net% effect formula, we can calculate the total perecntage for 3 years tenure = 33.1%**(sub details)**

So, the difference between SI and CI = 36% – 33.1% = 2.9% (SI is more)

Here Aditya will get, 2.9% of 10000 = 290

So Aditya will have Rs. 290 more than Bhushan.

---------------------------------------------------------------------------------

Net% effect = x + y = | xy | % |

100 |

For the first 2 years: Here, x = y = 10%

= 10 + 10 = | 10 × 10 | = 21% |

100 |

And for the next year: Here x = 21% and y = 10%

= 21 + 10 = | 21 × 10 | = 33.1% |

100 |

Hence, option C is correct.

C

This question requires no calculation

At the time the car enters the tunnel, the man is halfway into the tunnel. The time in which the man completed the other half of the tunnel, the car covered the whole tunnel. So it means that in the given time, car covered twice the distance that the man covered.

Distance = Speed × time

Since time is time taken is same in both the cases, it must be the speed.

So it is established that speed of car is twice that of the man

Speed of car = 2 × 20m/s = 40 m/s

Hence, option C is correct.

C

There is no need for calculation here.

Curved Surface Area can be calculated as – π × radius × slant height

We can see that CSA is directly proportional to the single power of slant height.

Since radii are equal, CSA are in proportion of the respective slant heights i.e 7 : 8.

Hence, option C is correct.
