14 persons earn Rs. 400 in 10 days. How many persons are required to earn Rs. 600.
Correct Option
Option C
Explanation
Earnings are proportional to number of persons, so required persons = 14*(600/400) = 21, hence 21 persons.
3147
If 25% proposals are rejected for a project, what is the ratio of number of proposals accepted to the number of proposals rejected ?

Option B
Explanation
Train speed = 60 km ÷ 1.5 hr = 40 km/hr; plane speed = 2×40 = 80 km/hr, and in 20 minutes (1/3 hr) it goes 80×1/3 = 26.67 km.

The mean of 5 observation is 60, the mean of 10 observation is 30 and the mean of 15 observations is 20. The mean of all 30 observations is: اردو: 5 مشاہدات کا اوسط 60 ہے، 10 مشاہدات کا اوسط 30 ہے اور 15 مشاہدات کا اوسط 20 ہے۔ تمام 30 مشاہدات کا اوسط ہے
Correct Option
Option D
Explanation
Totals: 5×60 + 10×30 + 15×20 = 300+300+300 = 900, and the mean = 900 ÷ 30 = 30.

3152
If the pth term of an AP is q and the qth term is p, prove that its nth term is (p + q - n).
Correct Option
Option C
Explanation
From a+(p−1)d = q and a+(q−1)d = p, subtracting gives d = −1 and then a = p+q−1, so the nth term a+(n−1)d = p+q−n.
Multiply both terms of 3:7 by 3 to get the equivalent ratio 9:21.
3155
Arithmetic mean between x -3 and x + 3 is:
Correct Option
Option B

One solving x+2y =13, x+y+z=12, 2y+z=11 answer will be?
Correct Option
Option B
Explanation
x=3, y=5, z=4: substituting gives x+2y = 3+10 = 13 and x+y+z = 3+5+4 = 12, but 2y+z = 10+4 = 14 which does not equal 11, so this triple does not satisfy all three equations.
