Q:

In a cricket match, five batsmen P, Q, R, S and T scored an average of 36 runs. S Scored 5 more than T; T scored 8 fewer than P; Q scored as many as S and T combined; and Q and R scored 107 between them. How many runs did T score ?

A) 20 B) 29
C) 28 D) 24
 
Answer & Explanation Answer: A) 20

Explanation:

Let the runs scored by P, Q, R, S and T be  a, b, c, d and e

From given data,

a + b + c + d + e = 36 x 5 = 180
b + c = 107
Let a = x
e = x-8
d = x-3
now 3x - 11 + 107 = 180
3x = 84
x = 28
e's score = 28-8 = 20

Q:

A sum of Rs.1890 has to be used to give 9 prizes to the customers of a super market for their overall academic purchases. If each prize is Rs.30 less than its preceding price, what is the least value of the price ?

A) 90 B) 95
C) 85 D) 80
 
Answer & Explanation Answer: A) 90

Explanation:

Let the least value of the prize = Rs. x
Then the next value of the prize is x+30 , x+60, x+90, ....x+240.
Given total amount of cash prizes = Rs.1890
 x + (x+30) + (x+60) + (x+90) + ....+ (x+240) = 1890
   9x + (30 + 60 + 90 + 120 + 150 + 180 + 210 + 240) = 1890
   9x + 30(1 + 2 + 3 + 4....+ 8) = 1890
   9x + 30(36) = 1890
  9x = 810  x=90
Hence the least value of the prize x=90
