For design of one material these four marbles are used in the proportion as given below. Blue Red Green Pink 40 % 20 % 25 % 15 % Each marble cost is increased by 25 %. Then, designer decided to reduce the no. of marbles used so that the total cost is same as before. Therefore, he reduced the same number marbles of each colour. What will be the percentage of proportion of blue marbles as per the new design? [Ans. 43.75%] 10. There are four friends P, Q, R, S. They have to cross the river. They have only one boat.
