Dear Student,
◆ Answer -
John has 198 marbles
● Explanation -
Let j, d and t be no of marbles John, David and Tom have respectively.
From given data,
j + d = 276 ...(1)
j + t = 432 ...(2)
t = 3d ...(3)
Substitute (3) in (2),
j + 3d = 432
3d = 432 - j
d = (432-j)/3
d = 144 - j/3 ...(4)
Substitute (4) in (1),
144 - j/3 + j = 276
2j/3 = 276 - 144
j = 132 × 3/2
j = 198
Therefore, John has 198 marbles.
Hope that's all...
