Answers
Question:
300 apples are distributed among A,B and C in such a way that three times of the number received by 'A' may be equal to four times of 'B' and nine times that of 'C'. The number of apples received by 'B' is ....
Answer:
108
Step-by-step explanation:
Total number of apples = 300
A + B + C = 300 ---------------------- [ 1 ]
3 times of the number received by 'A' equal to 4 times of 'B'
3A = 4B
4B = 3A
B = 3/4 A ---------------------- [ 2 ]
3 times of the number received by 'A' equal to 9 times that of 'C'.
3A = 9C
9C = 3A
C = 3/9 A
C = 1/3 A ---------------------- [ 3 ]
Sub [ 2 ] and [ 3 ] into [ 1 ] :
A + B + C = 300
A + 3/4 A + 1/3 A = 300
25/12 A = 300
25A = 3600
A = 3600 ÷ 25
A = 144
Sub A = 144 into [ 2 ]:
B = 3/4 A
B = 3/4 (144)
B = 108
Sub A = 144 into [ 3 ]:
C = 1/3 A
C = 1/3 ( 144)
C = 48
Answer: The number of apples received by 'B' is 108
