What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘× ‘ are interchanged and also ‘5’ and ‘9’ are interchanged?
 3 + 9 – 6 × 5 ÷ 3 = ? 

Select the correct combination of mathematical signs to replace the * signs and to balance the given equation.
 50 * 2 * 3 * 30 * 10 * 40 * 20

Direction: Some equations have been solved on the basis of certain system. Find the correct answer for the unsolved equation on that basis.

If 12 × 16 = 188 and 14 × 18 = 248, then find the value of 16 × 20 = ?

The second number in the given number pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) are followed in all the number pairs, EXCEPT one. Find that odd number pair.

Select the odd group of numbers. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 – Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)

Directions: There are six wires in a table A, B, C, D, E and F they have different length but not necessarily in the same order. E is greater than C but less than D and B. A is greater than D and B. A is not longest wire. F is 13 cm. long and E is 4 cm. long.

If D is 5cm less than F what would be the length of D?

Direction: Study the following information and answer the questions that follow.
