b. 25
c. 49
d. 16
Answer:- Option C the value of p=7 and p^2=49

Question 3:
Let x be the least number which when divided by 12,15,18,20,27 and 30, the remainder in each
case is 1 and x is a multiple of 47. The sum of the digits of x is:
Options:
a. 13
b. 11
c. 9
d. 10
Ans:- d) 10

LCM of 12,15,18,20,27, 30 is 540
Number should be divisible by 47 if we multiply k by 540 and add 1 then the number is divisible by 47
540k + 1/ 47
Put value of k as 1,2
For k=2
540 * 2 +1 = 1081 which is divisible by 47
1081/47=23
So the digit is 1081
Addition of digits = 10
