Direction: Ramesh and Suresh are two friends having two colored balls viz. Red and Green color. The number of balls with them for the month of January, February and March is given. The probability of choosing 2 balls of green color by Ramesh in the month of January is 133/1199 and the total number of red colored balls is twice that of the total number of green colored balls. The probability of choosing a red colored ball by Suresh in the month of March is 3/5. The total number of balls with Ramesh in the month of February is 200 more than the total number of balls with Suresh in the month of January. The total number of green colored balls with Ramesh in the month of March is same as the total number of red colored balls with Suresh in the month of February. Total number of green colored balls with Ramesh in the month of March is 7/5th of the total number of red colored balls with him in the same month. Total number of balls of different colors with Suresh in the month of January is equal. The total number of green colored balls with Ramesh in the month of February is 400 more than the total number of Red colored balls in the same month. The total number of red colored balls with Ramesh in the month of January is same as the total number of green colored balls with Suresh in the month of March. There are 1500 balls with Suresh in the month of February and the probability of choosing two green colored balls by Ramesh in the month of March is 1631/4796. The summation of the total number of Red colored balls with Ramesh in the month of February and the total number of red colored balls with Suresh in the month of January is equal to the total number of green colored balls with Ramesh in the month of February.
