Question 6 Explanation: 
one day combined work of P and Q= 1/30+1/60 = 1/20.
Thus P and Q can finish the work together in 20 days.
But they have worked only for 10 days which means they have finished half of the job.

So they will be paid half of the money= 500 rs

Question 7 Explanation: 
in base 10 we know 6+2= 8 but in this question it is given 1 so we have to find the base of these numbers.
Now let the base be x so 6+2=8 -x= 1 thus base =7 (because in base 7, 8 will be represented as 1 carry and 1 addition ).
Now subtracting given numbers in base 7. Mock_7

Question 8 Explanation: 
Explanation- let CP of A= x
SP price of A = 117x/100.
SP of b = SP of A – 25%of SP of A = 117x/100-117x/400 = 351x/400
351x/400=1053
x = 1200

Question 9 Explanation: 
here total cases will be 4!= 24.
Now cases in favour as per given question –
A    B    C    D (fix pen 2 in A)
2    1    4    3
2    4    1    3
2    3    4    1 - 3 cases
Just like that fixing pen 3 and 4 at A will produce 3 cases each.
Therefore total favourable cases will be 9.
Probability = 9/24 = 3/8
