A. 6a2 cm2
B. 8a2 cm2
C. 12a2 cm2
D. 24a2 cm2
Explanation:
6a2 = 6 * 2a * 2a = 24a2
A. 101
B. 107
C. 111
D. 185
Explanation:
Let the numbers be 37a and 37b.
Then, 37a * 37 b = 4107 => ab = 3
Now, co-primes with product 3 are (1, 3).
So, the required numbers are (37 * 1, 37 * 3) i.e., (1, 111).
Greater number = 111.
A. 20
B. 21
C. 22
D. 23
Explanation:
Let the total number of workers be x. Then,
8000x = (12000 * 7) + 6000(x – 7)
= 2000x = 42000
= x = 21
A. 3
B. 4
C. 5
D. 6
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. Rs. 81.60
B. Rs. 160
C. Rs. 1081.60
D. None of these
Explanation:
Principle = Rs.(8000/8) = Rs. 1000
Therefore, C. I = Rs. [{ 1000 × (1 +4/100)2 – 1000}]
= Rs. 81.60
A. 40
B. 400
C. 5040
D. 2520
