The length of rectangle is thrice its breadth and its perimeter is 96 m, find the area of the rectangle?
A. 432 sq m
B. 356 sq m
C. 452 sq m
D. 428 sq m
Explanation:
2(3x + x) = 96
l = 36 b = 12
lb = 36 * 12 = 432
A. 432 sq m
B. 356 sq m
C. 452 sq m
D. 428 sq m
Explanation:
2(3x + x) = 96
l = 36 b = 12
lb = 36 * 12 = 432
A. 720
B. 750
C. 820
D. 840
E. None of these
Explanation:
25% of x = x/4 ; 15% of 1500 = 15/100 * 1500 = 225
Given that, x/4 = 225 – 15 => x/4 = 210 => x = 840.
A. 2h
B. 4h
C. 2h/3
D. 3h/2
A. Rs.5000
B. Rs.4600
C. Rs.5400
D. Rs.2300
100x + 400 = 12(x – 5)
x = 50
100 * 50 + 400 = 5400
A. 5 hrs
B. 10 hrs
C. 15 hrs
D. 20 hrs
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. 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
