Possible teams = AD CB EB GB
AF CF ED GD
AH CH EH GF S
Since one male can be paired with 3 other female, Total teams = 4×3 = 12.
Team AD can play only with CB,CF,CH,EB,EH,GB,GF(7 teams )
Team AD cannot play with AF, AH, ED and GD
The same will apply with all teams, So number of total matches = 12×7 = 84.
But every match includes 2 teams, so the actual number of matches = 84/2 = 42.
A. Rs.29.25
B. Rs.30.25
C. Rs.32
D. Rs.35
Average of 9 = x
9x = 8 * 3 + x * 2 x = 3.25
Total = 9 * 3.25 = 29.25
A. 65 years
B. 56 years
C. 45 years

Simple interest is given by the formula SI = (pnr/100), where p is the principal, n is the numberof years for which it is invested, r is the rate of interest per annum
In this case, Rs. 1250 has become Rs.10,000.
Therefore, the interest earned = 10,000 – 1250 = 8750.
8750 = [(1250 x n x 12.5)/100]
=> n = 700 / 12.5 = 56 years.
A. 160
B. 200

D. 240
Let the number of 50p, 1 rupee and 2 rupee coins be 2x,5x and 8x. 0.5*(2x)+5x+2*8x = 352 22x=352 x=16 Total no. of coins
= 2x+5x+8x
= 15x = 240
