Raja sold T-shirts in 3 colours, black, yellow and white. He had 184 more yellow than white shirts. After selling 1/4 of the yellow shirts, he had 87 more yellow than black ones. The number of white shirts was 2/3 of the number of black ones. What was the total number of shirts he had at first?

B==Black, Y==Yellow, W==White
Y - W==184,
0.75Y - B ==87,
W ==2/3B, solve for B, Y, W


B==102, Y==252,  W==68
[102 + 252 + 68] ==422 - shirts altogether.
