ANSWERS With Solutions: 

1.    Answer: (A)

Percentage of money spend on Tennis = [(45 /360)] X 100% = 12 ½

2.    Answer: (A)

Let the total spending on sports be Rs. x. Then,

Amount spent on Golf = Rs  [(36x/ 360 )] = Rs. x/ 10

Amount spent on Hockey = Rs [ ( 63x/360)]= Rs. 7x /40

Difference = Rs. [(7x /40) – (x/10)]  = Rs 3x/40

Required percentage = Rs. [ (3x/40)/ x /10) * 100] % = 75%

3.    Answer: (A)

Amount spent on Basketball exceeds that on Tennis by:

Rs. [ (50 - 45)/ 360) * 1,80,00,000]= Rs. 2,50,000.

4.    Answer: (C)

Let the total spending on sports be Rs. x. Then,

Amount spent on Cricket = Rs [( 81/360) * x ) = Rs. 9x/40

Amount spent on Football = Rs [( 54/360) *x] = Rs. 3x/20

Difference = Rs. [ ( 9x /40) – ( 3x/20) ] = Rs. 3x/40

Required percentage = Rs. [ (3x/40/ 9x/40) * 100)] % = 33 1/3 %

5.    Answer: (C)

Let the amount of Royalty to be paid for these books be Rs. r.

Then, 20 : 15 = 30600 : r

    ð  r = Rs. 22,950

6.    Answer: (C)

Central angle corresponding to Royalty = (15% of 360)º

[(15/100) *360]⁰

= 54⁰

7.    Answer: (B)

Clearly, marked price of the book = 120% of C.P.

Also, cost of paper = 25% of C.P

Let the cost of paper for a single book be Rs. n.

Then, 120 : 25 = 180 : n

n =  Rs. 37. 50

8.    Answer: (A)

For the publisher to earn a profit of 25%, S.P. = 125% of C.P.

Also Transportation Cost = 10% of C.P

Let the S.P. of 5500 books be Rs. x.

Then, 10 : 125 = 82500 : x.

x = Rs. [(125 x 82500) x 10]= Rs. 1031250

S.P. of one book = Rs. (1031250/ 5500)= Rs. 187.50

9.    Answer: (D)

Printing Cost of book = 20% of C.P.

Royalty on book = 15% of C.P.

Difference = (20% of C.P.) - (15% of C.P) = 5% of C.P.

Percentage difference = [ (Difference/Printing) * 100%

= [ ( 5% of C.P./Printing Cost ) x 100%]

= 25%
