The cost of a pair of a roller skates at a shop was Rs.1700. If the sales tax charged was 5%, then the bill amount was
A)
Rs.1870
B)
Rs.1875
C)
Rs.1780
D)
Rs.1785
Sales tax = 5% of Rs.1700 = (5/100) × 1700 = Rs.85. Therefore, total bill amount = Rs.1700 + Rs.85 = Rs.1785. Hence, option (d) is correct. The other options do not match the sum after adding 5% sales tax.
A, B and C enter into business as partners and made a profit of Rs.1900. If A : B = 2 : 3, B : C = 2 : 3, find the share of B.
A)
Rs.550
B)
Rs.560
C)
Rs.600
D)
Rs.650
Let A:B = 2:3 and B:C = 2:3. Make B common in both ratios.
From A:B = 2:3, let A = 2x and B = 3x.
From B:C = 2:3, let B = 2y and C = 3y.
To make B equal, take B = 6 parts in both cases:
A:B:C = 4:6:9.
Total parts = 4 + 6 + 9 = 19.
Total profit = Rs.1900, so 1 part = 1900/19 = Rs.100.
Therefore, B's share = 6 × 100 = Rs.600.
So the correct option should be (c).
In what time will Rs.1250 amount to Rs.1400 at 6% per annum simple interest?
A)
2 years
B)
2 1/2 years
C)
3 years
D)
3 1/4 years
Simple interest = Amount - Principal = 1400 - 1250 = 150. Using SI = (P × R × T)/100, we get 150 = (1250 × 6 × T)/100 = 75T. Therefore, T = 150/75 = 2 years. Hence, the correct option is (a). Other options give a different interest amount, so they are incorrect.
In a school, the ratio of the number of boys to girls is 5 : 8. If there are 320 girls, then the number of boys is
A)
280
B)
275
C)
250
D)
200
The ratio of boys to girls is 5 : 8. This means 8 parts correspond to 320 girls. So, 1 part = 320 ÷ 8 = 40. Therefore, number of boys = 5 × 40 = 200. Hence, option (d) is correct. The other options do not satisfy the ratio 5 : 8 with 320 girls.

- (c) Decode: a process performed by the CPU, not its name.

If the price of tea is increased by 50%, by what per cent must a housewife reduce consumption, so as not to increase the expenditure of the family on tea ?
A)
33 1/3 %
B)
44 1/4 %
C)
55%
D)
55 1/5 %
Let the original price be 100 and original consumption be 100 units. Then original expenditure = 100 × 100 = 10000. After a 50% increase, new price = 150. To keep expenditure unchanged, new consumption = 10000/150 = 66 2/3 units. Reduction in consumption = 100 - 66 2/3 = 33 1/3 units, i.e. 33 1/3%. Hence the correct answer is option (a). Other options do not keep the total expenditure unchanged.
A tap ‘A’ can fill a cistern in 8 hours and another tap ‘B’ can empty the full cistern in 12 hours. If both the taps are opened together when the cistern is empty, then the time require to fill the cistern is
A)
20 hours
B)
22 hours
C)
24 hours
D)
27 hours
Tap A fills the cistern in 8 hours, so its filling rate is 1/8 cistern per hour. Tap B empties it in 12 hours, so its emptying rate is 1/12 cistern per hour. When both are opened together, the net rate is 1/8 - 1/12 = (3 - 2)/24 = 1/24 cistern per hour. Therefore, time taken to fill the cistern = 24 hours. Hence, the correct option is (c).
A gun is fired at a distance of 3.32km from Peyton. She hears the sound 10 seconds later. The speed of the sound is
A)
303m/s
B)
332m/s
C)
342m/s
D)
342m/s
Distance = 3.32 km = 3320 m. Time taken = 10 s. Speed of sound = Distance / Time = 3320 / 10 = 332 m/s. Therefore the correct option is (b) 332m/s. Option (a) is too low, and options (c) and (d) do not match the calculation.
What percentage is 390 g of 1 kg 500 g?
A)
20%
B)
22 %
C)
25 %
D)
26%
1 kg 500 g = 1500 g. Required percentage = (390 / 1500) × 100 = 26%. Therefore, the correct option is (d) 26%. The other options do not match this calculation.
