Test: Simplification- 1 - CUET Commerce MCQ

• First, calculate 8% of 800: 8/100 * 800 = 64.
• Now, the equation is 64 * ? = 224.
• To solve for ?, divide both sides by 64: ? = 224 / 64.
• This simplifies to ? = 3.5.
• So, the correct answer is 3.5, which corresponds to option 2.

Correct option is D. 9

On solving, we will get x = 3 or x = -2
Ignoring the negative value answer is 3.

√8-√4-√2=√2×4-√4-√2 =√4-√2=√2-2 ans

 5.5 x 6.4 / 0.4 =  35.2 / 0.4 = 88 

Solution:

Given equation:

(764 x ?) ÷ 250 = 382

Solving for ?:

(764 x ?) = 382 x 250

? = (382 x 250) / 764

? = 125

Therefore, the value of ? is 125.

So, the correct answer is B: 125.

C is the correct option. Solution- 
4028÷53=76
6156÷76=81
So the value needed is a square of 81 which is 6561.

[(7 x 9) + (2 x 12) + 3] / [(12 x 3) + (81 / 9)]
= (63 + 24 + 3) / (36 + 9)
= 90/45
= 2

To solve the given expression:

1. Calculate the values inside the parentheses first: √(169 - 144 = 25) and √(64 + 36 = 100).
2. Now simplify the expression further: √25/√100 .
3. Calculate the square roots: 5/10
4. Finally, divide the two results: 0.5

Therefore, the correct answer is A: 0.5.

Option (a) 2602 is correct. 

Explanation:- 
 

{ Given,   

-224 + ( - 314) * (-9) 

 According to BODMASS ; 

=>  -224 -314  * -9

=>  -224 +  2826
=>   2602

8/21 * x = 1008

x = 21168 / 8

x = 2646
