Box 2 contains Papaya and is placed just above Apple box. 3 boxes are placed between Box 4 and the box that has Orange. Orange box is placed adjacent to Papaya box and is above Box 4.With the given hints following cases are two possible: 
Therefore in absence of further hints, we cannot determine the box number of the boxes at third and fourth positions from top\ 
390/? = √256 + 3.5
116*2/3% of 18600 + 666*2/3% of 1290 = 457*1/7% of 1750 + 555*5/9% of 3150 + ?
60% of 3050 + 80% of 6050 =?
[4(1/3) + 4(1/4)] × 24 – 62 = ?2
3% of 3000 x?% of 2000 = 3600
What is 12% of 4% of 7% of 2 x 106 ?
81% of 2300 – 34% of 550 = ?
Ravi is 12 years younger than Surya. Ravi's age is 40% of the sum of his and Surya's age. What will be Surya's age 9 years hence?
560 ÷ 14 × 3 – 25 = ?
(120 × ?)/(36 × 0.2) = 200
