Let the four integers be A, B, C and D where A > B > C > D.
(A + B + C + D)/4 = 69 => A + B + C + D = 276 —> (1)
A = 93, D = 39 and B – C = 28
(1) => B + C = 276 – (A + D) = 276 – 132 = 144.
B + B -28 = 144
B = (144 + 28)/2 = 86
A. Rs. 992
B. Rs. 1112

D. Rs. 1182
Principal = 800 SI = 120 Time = 3 year
Rate = (100*120/800*3) = 5%
New rate = 8 % principal = 800 time 3 year
SI = (800*8*3/100) = 192
New amount = 800 + 192= 992

Explanation:
Number of sweets each child got = 15% of 80 = 15/100 * 80 = 12.
Number of sweets 80 children got = 80 * 12 = 960.
Number of sweets each youngster got = 25% of 80 = 25/100 * 80 = 20.
Number of sweets 10 youngsters got = 10 * 20 = 200.
Total number of sweets = 960 + 200 = 1160.
