The ratio between two numbers is 5 : 6. If 5 is subtracted from each number, the ratio becomes 4 : 5. The numbers are
A)
9, 10
B)
50, 60
C)
25, 30
D)
30, 36
Let the two numbers be 5x and 6x.
After subtracting 5 from each, the ratio becomes 4:5:
(5x - 5) / (6x - 5) = 4/5
Cross-multiplying:
5(5x - 5) = 4(6x - 5)
25x - 25 = 24x - 20
x = 5
So the numbers are 5x = 25 and 6x = 30. However, this pair is not among the options. Checking the options, the pair 30, 36 has ratio 5:6, and after subtracting 5 gives 25, 31, whose ratio is not 4:5.
Thus the intended correct pair from the equation is 25 and 30, which matches option (c).
Who becomes world’s highest paid Model in 2017?

B)

C)

D)

A sum of money will double itself in 16 years at simple interest with yearly rate of:
A)
10%
B)
6 %
C)
8%
D)
16%
For simple interest, SI = (P × R × T) / 100.
If a sum doubles itself, then the interest earned equals the principal: SI = P.
So, (P × R × 16) / 100 = P.
Cancel P on both sides:
16R / 100 = 1 → R = 100/16 = 6.25%.
But since 6.25% is not among the options, let's re-check the intended interpretation. In many exam questions of this form, the standard shortcut for doubling in T years at simple interest is R = 100/T. For 16 years, that gives 6.25%, which again is absent.
However, among the given options, none is exactly correct. If the question is taken as a common exam-style approximation or a misprint, the closest intended option is not reliable.
Since the options do not contain the correct value, the question appears defective.

B)

The other options incorrectly use 'Strategy' instead of 'Strategic' or add 'System/Station' in an unsuitable way.

A can do a work in 15 days and B in 20 days. If they work on it together for 4 days, then the fraction of the work left is
A)
1/4
B)
1/10
C)
7/15
D)
8/15
A’s 1-day work = 1/15 and B’s 1-day work = 1/20. Together, their 1-day work = 1/15 + 1/20 = 4/60 + 3/60 = 7/60. In 4 days, they complete 4 × 7/60 = 28/60 = 7/15 of the work. Therefore, the fraction of work left = 1 - 7/15 = 8/15. So the correct option is (d) 8/15. Note: the option list includes 8/15, which is the correct remaining work, while 7/15 is the completed work.

The number that must be added to each of the numbers 2, 3, 30 and 35, so that they are in proportion is
A)
2
B)
3
C)
5
D)
8
Let the required number be x. Then the numbers become 2+x, 3+x, 30+x, and 35+x. For them to be in proportion, we need (2+x)/(3+x) = (30+x)/(35+x). Cross-multiplying gives (2+x)(35+x) = (3+x)(30+x). Expanding: 70 + 37x + x^2 = 90 + 33x + x^2. So 4x = 20, hence x = 5. Therefore, the correct answer is 5. The other options do not satisfy the proportion condition.
100 ml of a 20 % solution of alcohol in water are mixed with 200 ml of a 50 % solution of alcohol in water. The alcoholic strength of the mixture solution is
A)
30 %
B)
35 %
C)
38 %
D)
40 %
Alcohol in the first solution = 20% of 100 ml = 20 ml. Alcohol in the second solution = 50% of 200 ml = 100 ml. Total alcohol = 120 ml, and total mixture = 100 + 200 = 300 ml. So alcoholic strength = (120/300) × 100 = 40%. Therefore the correct option is (d), not (a).
