A. 1300 m3
B. 1331 m3
C. 1452 m3
D. 1542 m3
6a2 = 726
=> a2 = 121
=> a = 11 Cm
Therefore, Volume of the cube
= (11 × 11 × 11) cm3 = 1331 cm3
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
A. Rs. 270
B. Rs. 290
C. Rs. 300
D. None of these
Explanation:
Marked price be Rs. X
Discount availed by the retailer = 15% of Rs. X
C.P of the machine by the retailer
= (X – 15% of X) = Rs. 17X/20
15% of 17X/20 = 1955 – 17X/20
51X/400 + 17X/20 = 1955 or
X = 2000 Discount received retailer
= (15% of Rs. 2000) = Rs. 300
A. 1305
B. 435
C. 875
D. 48
A. 6
B. 24
C. 96
D. 720
A. 32 hours
B. 48 hours
C. 3 days
D. 4 days
Part of task completed by A in a day = 1/x Part of task completed by B in a day = 3/x (B is thrice as efficient as A) (1/x)+(3/x) = 1 4/x = 1 x = 4 B completes 3/4th of the task in a day. He takes 4/3 days to complete the entire task. 4/3 days = (4/3*24) hours = 32 hours
A. Rs. 6
B. Rs. 6.48
C. Rs. 7.02
D. Rs. 7.20
Explanation:
90 : 5.40 :: 120 : x
X = (5.40 x 120)/90 = 7.20
