A. 3 dm
B. 4 dm

D. 6 dm
33 + 43 + 53 = a3 => a = 6
A. 2700
B. 1080
C. 450
D. 1800
Number of bottles produced by 1 machine in a minute
= 270/6 Number of bottles produced by 10 machines in 4 minutes
= (270/6)*10*4 = 1800
A. 3 pm
B. 2 pm
C. 1:00 pm
D. 11 am
Work done by P in 1 hour = 1/8
Work done by Q in 1 hour = 1/10
Work done by R in 1 hour = 1/12
Work done by P,Q and R in 1 hour = 1/8 + 1/10 + 1/12 = 37/120
Work done by Q and R in 1 hour = 1/10 + 1/12 = 22/120 = 11/60
From 9 am to 11 am, all the machines were operating.
Ie, they all operated for 2 hours and work completed = 2 × (37/120) = 37/60
Pending work = 1- 37/60 = 23/60
Hours taken by Q an R to complete the pending work = (23/60) / (11/60) = 23/11
which is approximately equal to 2
Hence the work will be completed approximately 2 hours after 11 am ; ie around 1 pm
A. 50
B. 52
C. 58
D. 60
Explanation:
Let the number be x.
Then, x – 16% of x = 42.
x – 16/100 x = 42
x = (42 * 25)/21 = 50
A. 24
B. 36
C. 48
D. None of these
Explanation:
(830 + ? * 3 * 14 / 100) – (830 * 14 * 3 / 100) = 20.16
=> 830 + ? * 42 – 830 * 42 = 2016
=> ? * 42 = 2016 + 830 * 42 – 830
=> ? * 42 = 42 * 48 + 830 * 42 – 830
=> ? = 48 + 830 – (830 / 42)
=> ? = 48 + 830 – 19.76
=> ? = 858.24
A. Rs. 5400
B. Rs. 7200
C. Rs. 8400
D. Rs. 9600
Explanation:
Ratio of their s = 22500 : 35000 = 9:14
Raees’s = 13800 * 14/23 = Rs. 8400.
