A. 1000
B. 600
C. 2400
D. 1200
50/100 * x = 30 * 20 => x = 1200
A. 1 13/17 hours
B. 2 8/11 hours
C. 3 9/17 hours
D. 4 1/2 hours
Explanation:
Net part filled in 1 hour = 1/5 + 1/6 – 1/12 = 17/60
The tank will be full in 60/17 hrs, i.e., 3 9/17 hrs.
A. 8000
B. 8010
C. 8020
D. 8040
Explanation:
(2000 + 3)(2000 + 4) – (2000 + 1)(2000 + 2) = ?
Since (2000 * 2000) – (2000 * 2000) is equal to zero. ?
= (8000 + 6000 + 12) – (4000 + 2000 + 2)
=> ? = 14012 – 6002 = 8010
A. 9 min
B. 10 min
C. 11 min
D. 12 min
4/12 + x/15 = 1
x = 10
A. 32 kg
B. 40 kg
C. 52 kg
D. 80 kg
Explanation:
Quantity of water in 100kg of fresh fruits =(68/100 × 100)kg
Quantity of pulp in it = (100 – 68)kg = 32 kg
Let the dry fruit be x kg
Water in it = (20/100 × x)kg = x/5 kg
Quantity of pulp in it = (x – x/5)kg = 4x/5 kg
Therefore, 4x/5 = 32 => x = 160/4 = 40 kg
A. 855 1/2 grams
B. 833 1/3 grams
C. 833 1/2 grams
D. 875 2/7 grams
Explanation:
If the cost price is Rs.100, then to get a profit of 20%, the selling price should be Rs.120.
If 120kg are to be sold, and the dealer gives only 100kg, to get a profit of 20%.
How many grams he has to give instead of one kilogram(1000 gm).
120 gm —— 100 gm
1000 gm —— ?
(1000 * 100)/120 = 2500/3 = 833 1/3 grams.
A. Rs.4400
B. Rs.4445
C. Rs.4460
D. Rs.4520
Explanation:
Sum be P
P(1 + R/100)3 = 6690 – (i)
P(1 + R/100)2 = 10, 035 – (ii)
By dividing (i) and (ii)
(1 + R/100)3 = 10035/6690 = 3/2
Therefore, P = (6690 x 2/3) = Rs. 4460
