Test: Simplification- 5 - SSC CGL MCQ

69 ÷ 3 * 0.85 = 23 * 0.85 = 19.55
19.55 + 14.5 – 3 = 31.05

So option E is correct

17.68 * 0.5 = 8.84
42.58 – 8.84 = 33.74

So option B is correct

To solve the problem:

1. Add 23.56 and 4142.25:
   • Whole numbers: 23 + 4142 = 4165
   • Decimals: 0.56 + 0.25 = 0.81
   • Total: 4165.81
2. Add the result to 134.44:
   • Whole numbers: 4165 + 134 = 4299
   • Decimals: 0.81 + 0.44 = 1.25
   • Adding decimals to whole number: 4299 + 1.25 = 4300.25

Thus, the correct answer is D. 4300.25.

√7744 = 88
(√7744 * 66) = 5808; 

5808/352 = 16.5

So option E is correct

(786*74) ÷ x = 1211.75
x = 48

So option D is correct

18² + √? = 350
√? = 350 – 324 = 26
? = 676

So option A is correct

140% of 500 is 700

24% of 750 is 180

700 + 180 = 880

So option D is correct

4900 ÷ 28 = 175
444 ÷ 12 = 37
175 * 37 = 6475

So option C is correct

First, calculate the sum of 1221 and 1117:

• 1221 + 1117 = 2338

Next, determine what percentage 2338 is of 6680 using the formula for percentage:

• x% = (2338 / 6680) × 100
• x% = 0.35 × 100
• x% = 35%

Since none of the provided options (26, 32, 43, 17) match the calculated value of 35%, the correct answer is not among the given choices.

To solve the problem, follow these steps:

• Compute √3840.56 ≈ 62.
• Calculate (501.01)² = 251,011.0201.
• Divide by 250: 251,011.0201 / 250 ≈ 1004.44408.
• Multiply all components: 62 × 1004.44408 × 0.987 × 1000 ≈ 61,457,110.

None of the options A-D (56, 76, 43, 51) match the result. Therefore, none are correct.

1/[2 + (1/(4+(1/(5 – 1/3))))] = 1/[2+(1/(4+(3/14)))] = 1/[2+(14/59)] =1/[118+14/59] =1/(132/59)
=59/132

So option D is correct

1399.99 ÷ 20.21 = ? + 425.5 - (310 ÷ 6 × 20.3)
(1400/20) = x + 426 – (312/6) * 20
70 – 426 + 1040 = x
x = 684 = 680 

To find the cube root of 0.000001728, we calculate a number x such that:

x³ = 0.000001728.

Testing option A:

• 0.012 × 0.012 × 0.012 = 0.000001728.

Thus, the correct answer is 0.012, which corresponds to option A.

2/3 + 8/9 - 21/15 

28/18 - 21/15

140-126/90

7/45 = 0.15

So option A is correct

0.4 *1124 = 449.6 = 450
450-9 = 441
441 = 21*21

So option C is correct

2ab = (a² + b²) – (a – b)²
2ab = 53-49 =4
ab =4/2 = 2

So option E is correct

The final answer to the problem, after calculating each percentage and summing them appropriately, results in 1115.6. However, since this exact value isn't among the provided options and considering typical examination practices where rounding may be applied, the closest option is:

• B

17*756÷54 = ? +540
17*14 = ? +540
238 = ? + 540
? =238-540 = -302

So option C is correct

= √(337/21 )÷ √(1365/84) × 26
= 16÷16 ×26 = 26

So option A is correct
