44. (b) To be above board: business Total = 2400+500=2900
agreement which is honest and not trying to After increasing, cost of 8 TV = 2640
deceive anyone. Cost of 5 music system = 550
45. (b) To put one's hand to plough: to do a Total increase = 2900-(2640+550)=290
difficult task. 290 × 100% = 10%

50. (a) Preceding is the proper spelling. 12 divided by 3 = 36

− = 46.50 B = 1.25 A

31 B works 25% more than A.
⇒ = 46.50
1000 a - amount paid to worker A.
⇒ = 1500 b - amount paid to worker B.
52. (c) If two articles are sold at same price, Set 3: a + b = 1800
one at a loss of R% and another at a profit of a + 1.25a = 1800
2 a = $800
R%, then there will always be a net loss of .
100 b = $1000
20 2
⇒ = = 4% 56. (b) Since ratio of efficiency of A, B, C =
100 4:5:6
Alternate method:
Let SP of 1st horse = 240 & SP of 2nd horse = We know that who is more efficient will take
240 less time to complete work.
240 So, the ratio of the time taken by A, B and C will
CP of first horse = × 100 = 200
120 be reciprocal of the ratio of efficiency of A, B
240
CP of 2nd horse = × 100 = 300 and C = LCM of 4, 5, 6 = 60
80
Total Cost Price = 200 + 300 = 500 Thus, the ratio of their times will be 15:12:10
Total Selling Price = 240 + 240 = 480 57. (a) As 8 dozen eggs cost Rs. 480, so 1 egg
480
Net Loss = 500 - 480 = 20 will cost = 5 i.e. Rs 5
20 8×12
⇒ × 100 = 4% As profit of man should be 10% which means
500 he should sell all eggs at Rs 480 + 480 × 10 =
53. (c) Let initial cost of music system = 100 100
Cost of TV = 300 528 i.e. Rs 528
After price increasing, Cost of TV = 330 As 8 of his eggs are found broken so left eggs
Cost of music system = 110 are 12 × 8 − 8 = 88
Initial cost of 8 TV = 2400 So, he has to sell 88 eggs in Rs 528 to earn 10%
Initial cost of 5 music = 500 profit
