Answers & Solutions:

1) Answer (A)

By applying BODMAS we have
=21+(68÷17)
=21+4
=25

2) Answer (D)

By applying BODMAS we have
(31/3)×15
=31×5
=155

3) Answer (B)

(19÷19  of  13) of 16=(19÷127)  of  16

=19×27  of  16

=3×16=12

4) Answer (C)

360? + 4500 = 19700 – 9800

360?+4500=9900

360?=5400

?=15

?=152

?=225

5) Answer (E)

Expression : 45.709÷11.342×6.667=?

= 4411×7

= 4×7=28

27

6) Answer (E)

Expression : 54.786÷10.121×4.454=?

= 5510×4.5

= 24.7524

7) Answer (E)

Expression : 59.786÷14.444×8.321=?

= 6015×8

= 4×8

= 3234

8) Answer (C)

Expression : 4275÷496×(21)2=?

= 4275×441495

= 3808.63 3810

9) Answer (A)

Since an approximate answer is sufficient, you can rewrite the question as 10000÷50×521130

Following BDMAS rule the result is 3870.

The nearest value is 3800.

Hence Option A is the correct answer.

10) Answer (E)

Let the number to replace the question mark be equal to X

Hence, 695.95÷29.07×X+40.25=399.99

399.99400 and 695.95696 and 29.0729

So, the expression looks like 696÷29×X+40=400
Hence, 24×X=360 or X=15

11) Answer (E)

Let the number to come in place of the question mark be equal to X

So, 29.38×37.05÷X+7.45=100.5
Or, 29.38×37.05÷X=93.05
So, X=29.38×37.0593.05=11.6912

12) Answer (C)

Let x be the value of the unknown number.

x= 987624.96 + 215.005 – 309.99

= 395.67 – 94.985 =≈ 300
