Select the correct combination of mathematical signs to replace the * signs and to balance the given equation.
 39 * 4 * 61 * 18 * 4 * 49 * 7 * 30

Select the correct combination of mathematical signs to replace the * signs and to balance the given equation.
 42 * 4 * 69 * 3 * 29 * 60 * 5

Study the given pattern carefully and select the number that can replace the question mark (?) in it.
 First row: 86, 72, 158
 Second row: 98, 111, 209
 Third row: 76, 65, ?
 (NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits. For example, 13 – Operations on 13 such as adding/deleting/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.)

Select the correct combination of mathematical signs to sequentially replace the * signs and balance the given equation.
 33 * 4 * 15 * 3 * 61 = 188

In a certain code language, ‘CRUST’ is written as ‘201921183’ and ‘BLAME’ is written as ‘5131122’. How will ‘PLASTIC’ be written in that language?

Directions: Study the following information carefully and answer the questions that follow:

Nine boxes A, B, C, D, E, F, G, H, and I are kept one above the other not necessarily in the same order. Three boxes are kept between A and B. Equal number of boxes are kept above and below A. Number of boxes kept above B is same as the number of boxes kept below C. Only two boxes are kept between C and I. One box is kept between A and G, which is not kept immediate above I. No box is kept between F and D,  which is not kept above F.  E is placed below H, which is kept immediate below D.

Which of the following statement is / are true?

By interchanging the given two signs, which of the following equations will NOT be correct?
 × and –
 I. 17 – 21 + 86 ÷ 2 × 13 = 387
 II. 10 + 63 – 12 × 259 ÷ 7 = 739

Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number.
 24 : -192 :: -31 : 248 :: -18 : ?
