Let assume the game has P points.
Then A has P points , B has (P ? 15) and C has (P ? 22) points and also if B has P points then C has (P ? 10) points.
Applying chain rule,
P x P ( P ? 22 ) = P ( P ? 15) ( P ? 10)
? P2 ? 22P = P2 ? 25P + 150
? 3P = 150
? P = 50
U ? A = {a, b, c, d, e, f} ? {a, b, c} = {a, b, c, d, e, f} = U
(U ? A)? = ?.
Sunil's income is less than Mukul's = [(10 / (100 + 10)] × 100 %
= ( 1000 / 110 )%
= 9.09 %
So, 39 is wrong.
So, 33 is wrong. It must be 35
∴ x = 7.
So, 40 is wrong.
