The tax on a commodity is diminished by 20% but its consumption is increased by 10%. Find the decrease percent in the revenue derived from it?

A. 20%
B. 18%
C. 15%
D. 12%
Explanation:
100 * 100 = 10000
80 * 110 = 8800
10000——- 1200
100 ——- ? = 12%

The ratio of the number of boys and girls is 3:2 if 20 % of the boys and 30 % of the girls are scholarship holders then the percentage of students who do not get scholarship is_________?

The ratio of the number of boys and girls is 3:2 if 20 % of the boys and 30 % of the girls are scholarship holders then the percentage of students who do not get scholarship is_________?

A. 50
B. 72
C. 75
D. 76
Explanation:
Let the number of boys be 3x and number of girls be 2x.
Number of scholarship holders
= (20/100 ×3x+ 30/100 ×2x) = 6x/5
Number of those who do not hold scholarship
= (5x- 6x/5) = 19x/5
Required percentage = (19x/5 × 1/5x ×100) % = 76 %

Aleem buys 4 horses and 9 cows for Rs. 13,400. If he sells the horses at 10% profit and the cows at 20% profit, then he earns a total profit of Rs. 1880. The cost of a horse is:_________?

Aleem buys 4 horses and 9 cows for Rs. 13,400. If he sells the horses at 10% profit and the cows at 20% profit, then he earns a total profit of Rs. 1880. The cost of a horse is:_________?

A. Rs. 1000
B. Rs. 2000
C. Rs. 2500
D. Rs. 3000
Explanation:
Let C.P. of each horse be Rs. x and C.P. of each cow be Rs. y.
Then, 4x + 9y = 13400 — (i)
And, 10% of 4x + 20% of 9y = 1880
2/5 x + 9/5 y = 1880 => 2x + 9y = 9400 — (ii)
Solving (i) and (ii), we get : x = 2000 and y = 600.
Cost price of each horse = Rs. 2000.

The speed of a motor boat is that of the current of water as 36:5. The boat goes along with the current in 5 hours 10 min, it will come back in_______?

The speed of a motor boat is that of the current of water as 36:5. The boat goes along with the current in 5 hours 10 min, it will come back in_______?

A. 5 hours 50 min
B. 6 hours
C. 6 hours 50 min
D. 12 hours 10 min
Explanation:
Let the speed of motor boat be 36x km/hr and that of current of water be 5x km/hr
Speed downstream = (36x +5x)km/hr = 41x km/hr
Speed upstream = (36 -5x)km/hr = 31x km/hr
Distance covered downstream = (41x × 31/6)km
Distance upstream = [1271x/6 × 1/31x]hrs
= 41/6 hrs = 6hrs 50 min
