Ans 1: (Master Answer)
(C):
After interchanging the bars for green
colour and red colour,
Number of brown colour marbles = 50
Number of green colour marbles = 20
Number of blue colour marbles = 80
Number of red colour marbles = 110
Number of yellow colour marbles = 60
(i) Actual difference between the number of red coloured and yellow coloured marbles = 110 - 60 = 50
(ii) Sum of brown, green and blue coloured marbles he actually has = 50 + 20 + 80 = 150
