Spent on family = 0.66 * S

Remaining = S - 0.66 S = 0.34 * S

given to the trust = 0.20 * 0.34 *S = 0.068 * S

What is left = 0.80 * (0.34 * S) = 0.272 S

0.272 * S = 12, 240 Rs

S = Rs 45, 000

given to trust = 0.068 * S = Rs 3, 060

Spent on family = 0.66x

Remaining = x - 0.66x = 0.34x

given to the trust = 0.20 * 0.34x = 0.068 x

What is left = 0.80(0.34x) = 0.272x

0.272x = 12, 240 Rs

x = Rs 45, 000

given to trust = 0.068x = Rs 3, 060
