There are 2400 red, blue and green marbles in Box A and Box B. In Box A, there are 25% as many red marbles as the total of blue and green marbles. There are twice as many marbles in Box A as Box B. 60% of the marbles in Box B were blue and green. After transferring some marbles from one box to another, 25% of the marbles in Box A and 75% marbles in Box B were red. How many marbles were there in Box A after the change?

Hi, please help. TIA


There are two concentric circles (circles with the same centres) and a square in the following diagram. The four corners A, B, C and D of the square lie on the bigger circle. The four midpoints W, X,Y and Z of the sides of the square lie on the smaller circle. If the smaller circle has area 314m2, find the (a) area of square ABCD and (b) area of the bigger circle. (take pi = 3.14)
