A. 785600
B. 315000
C. 845000
D. 442000
Explanation:
105 * 99 * 299 = 105 * 100 * 300 = 315000
A. 8/15
B. 7/15
C. 11/15
D. 2/11
Amount of work P can do in 1 day = 1/15
Amount of work Q can do in 1 day = 1/20
Amount of work P and Q can do in 1 day = 1/15 + 1/20 = 7/60
Amount of work P and Q can together do in 4 days = 4 × (7/60) = 7/15
Fraction of work left = 1 – 7/15= 8/15
A. 9:19
B. 19:9
C. 15:28
D. 28:15
Let A1 be the area of flat and A2 be that of the commercial space
Total cost = area * rate
Therefore, cost of flat = A1*4500 ; cost of commercial space = A2*9500
Both the above costs are same
A1*4500 = A2*9500
A1:A2 = 9500:4500 = 19:9
A. 1
B. 3/2
C. 2
D. 5/2
Explanation:
(64 + 9 + 9) / (2 * 20 + 1) = 82/41 = 2
A. 648
B. 888
C. 928
D. 1184
Explanation:
B has 62.5% or (5/8) of the water in A. Therefore, let the quantity of water in container A(initially) be 8k.
Quantity of water in B = 8k – 5k = 3k.
Quantity of water in container C = 8k – 3k = 5k
Container: A B C
Quantity of water: 8k 3k 5k
It is given that if 148 liters was transferred from container C to container B, then both the containers would have equal quantities of water.
5k – 148 = 3k + 148 => 2k = 296 => k = 148
The initial quantity of water in A = 8k = 8 * 148 = 1184 liters.
A. 3180
B. 3200
C. 3120
D. 3210
Explanation:
√3600 * 52 = ?
=> ? = 60 * 52 = 3120
