Simplification-Test 9 (Complete Revision)

Answer: Option C

Explanation

In this above question,

we apply VBODMAS rule,

= 38+16×0.8

=38+12.8

=50.8

Hence, Option C is correct.

Answer: Option A

Explanation

Here,

we apply VBODMAS rule,

$$\begin{gathered} = 1485\times ?=594 \\ =\frac{1485}{594}=? \\ =\frac{2}{5}=? \end{gathered}$$

Hence, Option A is correct.

Answer: Option D

Explanation

Here, 

we apply VBODMAS rule,

= 2116+692-?=1111

= -? =1111-2116-692

=-? = -1697

= ? = 1697

Hence, option D is correct.

Answer: Option C

Explanation

From the above question

Given that,

= 4+4.44+0.4+44.04+444

=496.88

Hence, Option C is correct.

Answer: Option E

Explanation

From the above question

we apply VBODMAS rule,

= (?)²+(65)²=(160)²-(90)²-(7191)

= (?)²=(160)²-(90)²-(7191)-(65)²

= (?)²=25600-8100-7191-4225

= (?)²= 6084

= ? =√6084

= ? = 78

Hence, Option E is correct.
