A. 125
B. 525
C. 25/64
D. 625
Explanation:
(25 * 25)/25 + 15 * 40 = 25 + 600 = 625.
A. 1:2
B. 3:5
C. 1:3
D. 3:4
72 should be divisible by addition of the above ratio.
Using trial and error method
For (a): – 1+2 = 3, 72 is divisible by 3
For (b): – 3+5 = 8, 72 is divisible by 8
For (a): – 1+3 = 4, 72 is divisible by 4
For (a): – 3+4 = 7, 72 is not divisible by 7
Therefore, the answer is option (d)
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. 1400
B. 1300
C. 1200
D. 1100
Explanation:
CP* (76/100) = 912
CP= 12 * 100 => CP = 1200
A. 25%
B. 50%
C. 20%
D. 5%
E. None of these
Explanation:
L.C.M of 15 and 12 = 60
CP of 60 articles = Rs. 100 (25 * 4)
SP of 60 articles = Rs. 150 (30 * 5)
Profit percentage = (150 – 100)/100 * 100 = 50%
A. 39
B. 40
C. 37
D. 35
Explanation:
HCF of 1189, 1073 = 29
1073/29 = 37
A. 53000
B. 58000
C. 50000
D. 59000
Explanation:
Interest received by A from B = 10% of half of Rs.50000 = 10% * 25000 = 2500.
Amount received by A per annum for being a working partner = 1500 * 12 = Rs.18000.
Let ‘P’ be the part of the remaining profit that A receives as his . Total income of A = (2500 + 18000 + P)
Total income of B = only his from the remaining profit = ‘P’, as A and B the remaining profit equally.
Income of A = Twice the income of B
(2500 + 18000 + P) = 2(P)
P = 20500
Total profit = 2P + 18000
= 2*20500 + 18000 = 59000
