52. If 5 tomatoes are worth 8 oranges,5 oranges are worth 4 apples, 7 apples are worth 3 pineapples and 7 pineapples cost rs.203,then the approx price of each tomato is?
Answer:
Explanation:Let, 7 pineapples cost = Rs.203
So, 1 pineapple = 203/7 = 29rs
Therefore, 3 pineapples = 29*3 =87rs
So, 7 apples = 87rs
Therefore, 1 apple = 87/7 = 12.42rs
And 4 apples= 12.42*4 = 49.71rs
So, 5 oranges = 49.71rs
Therefore, 1 orange = 49.71/5 = 9.94rs
And, 8 oranges = 9.94 * 8 = 79.54
Therefore, 5 tomatoes = 79.54
So, 1 tomatoe = 79.54/5 = 15. 90 rs.
Approx 16rs per tomato.
