The average weight of A, B, C and D is 33 kg. C is 12 kg lighter than A, while B is 6 kg heavier than C. D's weight is
10 kg less than that of C. What is the average weight of A and D?
A, B, C और D का औसत भार 33 kg है। C, A से 12 kg हल्का है, जबकि B, C से 6 kg भारी है। D का भार,
C से 10 kg कम है। A और D का औसत भार कितना है?
Correct Answer:
A + B + C + D = 132
C = A - 12
B = C + 6 OR B = A - 6
D = C -10 = A - 22
A + A - 6 + A - 12 + A - 22 = 132
4A = 172
A = 43, D = 43 - 22 = 21
Average of A and D = 32
A + B + C + D = 132
C = A - 12
B = C + 6 OR B = A - 6
D = C -10 = A - 22
A + A - 6 + A - 12 + A - 22 = 132
4A = 172
A = 43, D = 43 - 22 = 21
A और D का औसत = 32
