Correct Answer: 3 : 2
Explanation:
For dividing 12 into two whole numbers, the sum of the terms of the ratio must be a factor of 12. so, they cannot be in the ratio 3 :2.
Correct Answer: 437
Explanation:
Given number series is 514 470 ? 415 404
Here the pattern it follows is
514
514 - 44 = 470
470 - 33 = 437
437 - 22 = 415
415 - 11 = 404
Hence, the missing number in the given number series is 437.
Correct Answer: 0.05
Explanation:
Let 0.8 : 0.2 : : 0.2 : N
Then 0.8 x N = 0.2 x 0.2
? N = ( 0.2 x 0.2) / 0.8 = 0.04 / 0.08 = 4/80 = 0.05
Correct Answer: 14
Explanation:
Given Number series is :
3 4 14 48 576 27648
It follows a pattern that,
3
4
4 x 3 = 12 but not 14
12 x 4 = 48
48 x 12 = 576
576 x 48 = 27648
Hence, the odd one in the given Number Series is 14.
Correct Answer: 10
Explanation:
Here the given number series is 6, 3, 3, 4.5, 10
The odd one in the given series is 10
The pattern it follows is
6
6 x 0.5 = 3
3 x 1 = 3
3 x 1.5 = 4.5
4.5 x 2 = 9
Hence, the odd number is 10.
Correct Answer: 2
Explanation:
Let the number be N,
From question, (6 + N) / (14 + N) = (18 + N) / (38 + N)
? (6 + N) x (38 + N ) = (18 + N ) x (14 + N )
? N2 + 44N + 228 = N2 + 32N + 252
? 12N = 24
? N = 2
Correct Answer: 1500
Explanation:
Let the total profit be Rs. 100.
After paying to charity, A's share = (95*3/5) = Rs. 57.
If A's share is Rs. 57, total profit = Rs. 100.
If A's share is Rs. 855, total profit = (100/57*855) = 1500.
Correct Answer: 5 : 6 : 10
Explanation:
Let their initial investments be x, 3x and 5x respectively. Then,
A:B:C = (x*4+2x*8) : (3x*4+(3x/2)*8) : (5x*4+(5x/2)*8)
20x : 24x : 40x = 5 : 6 : 10
Correct Answer: 10 months
Explanation:
Let the total profit be Rs. z. Then,
B's share = Rs. 2z/3, A's share = Rs. ( z - 2z/3 ) = Rs. z/3.
A : B = z/3 : 2z/3 = 1:2
Let the total capital be Rs, X and suppose B's money was used for x months. Then.
(1(x) / 4 * 15) / (3x) / 4 * y) = 1/2 <=> y = (15 * 2 / 3) = 10 .
Thus, B's money was used for 10 months.
Correct Answer: 6 : 4 : 3
Explanation:
Let 2A = 3B = 4C = x
Then A = x/2, B = x/3 and C = x/4
? A : B : C = x/2 : x/3 : x/4
Hence A : B : C = 6 : 4 : 3
