The taxi charges in a city comprise of a fixed charge, together with the charge of the distance covered. For a journey of 16 km, the charges paid are $156 and for a journey of 24 km, the charges paid are $204. What will a person have to pay for travelling a distance of 30 km?

A.

$236

B.

$240

C.

$248

D.

$252

Correct answer is B

Let the fixed charge be $x and variable charge be $y per km. Then,

x + 16y = 156 ...(i) and

x + 24y = 204 ...(ii)

Solving (i) and (ii), we get: x = 60, y = 6.

Therefore Cost of travelling 30 km = 60 + 30 y = $(60 + 30 x 6) = $240.

A player holds 13 cards of four suits, of which seven are black and six are red. There are twice as many diamonds as spades and twice as many hearts as diamonds. How many clubs does he hold ?

A.

4

B.

5

C.

6

D.

7

Correct answer is C

Clearly, the black cards are either clubs or spades while the red cards are either diamonds or hearts.

Let the number of spades be x. Then, number of clubs = (7 - x).

Number of diamonds = 2 x number of spades = 2x;

Number of hearts = 2 x number of diamonds = 4x.

Total number of cards = x + 2x + 4x + 7 - x = 6x + 7.

Therefore 6x + 7 = 13 ⇔ 6x = 6 ⇔ x = 1.

Hence, number of clubs = (7 - x) = 6.

Aruna cut a cake into two halves and cuts one half into smaller pieces of equal size. Each of the small pieces is twenty grams in weight. If she has seven pieces of the cake in all with her, how heavy was the original cake ?

A.

120 grams

B.

140 grams

C.

240 grams

D.

280 grams

E.

None of these

Correct answer is C

The seven pieces consist of 6 smaller equal pieces and one half cake piece.

Weight of each small piece = 20 g.

So, total weight of the cake = [2 x (20 x6)]g= 240 g.
