Let the number of red jelly and yellow jelly in the box be ‘x’ and ‘y’ respectively. According to the question, {x/(5 + x + y)} = 3/10 Or, 7x – 3y = 15….. (1) Also, {y/(5 + x + y)} = 1/5 Or, 4y – x = 5……. (2) On solving equation (1) and (2), we get x = 3 and y = 2 Therefore, total number of jelly = 5 + x + y = 10
