A. Rs.3600
B. Rs.3700
C. Rs.3800
D. Rs.3900
Explanation:
Area = (l + b – d) d
(80 + 60 – 10)10 => 1300 m2
1300 * 3 = Rs.3900
A. 42.75%
B. 31.25%
C. 35.5%
D. 40.5%
E. None of these
Explanation:
Let the required percentage be x%.
3/20 = x% of 12/25 => 3/20 = x/100 * 12/25
=> 12x = (300 * 25)/20 => x = (25 * 25)/20
=> x = 31.25%.
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
