1) 8

2) 6

3) 12

4) 15

5) None of these

###### Answer

Answer –**2) 6**

**Solution:**

In first step:

Multiply 1st and 2nd number of box 1 and 4 respectively: 5 × 4 = 20

Multiply 2nd and 1st number of box 1 and 4 respectively: 3 × 2 = 6

Multiply 1st and 2nd number of box 2 and 5 respectively: 7 × 3 = 21

Multiply 2nd and 1st number of box 2 and 5 respectively: 2 × 4 = 8

Multiply 1st and 2nd number of box 3 and 6 respectively: 6 × 7 = 42

Multiply 2nd and 1st number of box 3 and 6 respectively: 2 × 3 = 6In second step:

Add 1st and 3rd number of box 1 and subtract it from 2nd number of box 1 = 6 + 2 = 8, 8 – 0 = 8

Add 1st and 3rd number of box 2 and subtract it from 2nd number of box 2 = 8 + 2 = 10, 10 – 1 = 9

Add 1st and 3rd number of box 3 and subtract it from 2nd number of box 3 = 6 + 4 = 10, 10 – 2 = 8In third step:

Divide 2nd number from 1st number = 9 ÷ 8 = 1.12

Divide 3rd number from 2nd number = 8 ÷ 9 = 0.89In fourth step:

Subtract both the numbers = 1.12 – 0.89 = 0.23

In first step:

Multiply 1st and 2nd number of box 1 and 4 respectively: 6 × 4 = 24

Multiply 2nd and 1st number of box 1 and 4 respectively: 4 × 1 = 4

Multiply 1st and 2nd number of box 2 and 5 respectively: 4 × 7 = 28

Multiply 2nd and 1st number of box 2 and 5 respectively: 3 × 3 = 9

Multiply 1st and 2nd number of box 3 and 6 respectively: 3 × 6 = 18

Multiply 2nd and 1st number of box 3 and 6 respectively: 8 × 1 = 8In second step:

Add 1st and 3rd number of box 1 and subtract it from 2nd number of box 1 = 4 + 2 = 6, 6 – 4 = 2

Add 1st and 3rd number of box 2 and subtract it from 2nd number of box 2 = 9 + 2 = 11, 11 – 1 = 3

Add 1st and 3rd number of box 3 and subtract it from 2nd number of box 3 = 8 + 1 = 9, 9 – 8 = 1In third step:

Divide 2nd number from 1st number = 3 ÷ 2 = 1.5

Divide 3rd number from 2nd number = 1 ÷ 3 = 0.33In fourth step:

Subtract both the numbers = 1.5 – 0.33 = 1.17

**Which is the largest number obtained in step 1?**

1) 188

2) 244

3) 249

4) 289

5) 250

###### Answer

**If the third number of all the boxes is halved and then added the half numbers, what is the result in step 1?**

1) 10.5

2) 12.5

3) 8.5

4) 11.5

5) None of these

###### Answer

Answer –**1) 10.5**

**What is the sum of numbers in step 3?**

1) 0.66

2) 0.74

3) 1.83

4) 1.66

5) 1.35

###### Answer

Answer –**3) 1.83**

**Which is the following number obtained in last step?**

1) 1.07

2) 1.77

3) 1.67

4) 1.17

5) None of these

###### Answer

Answer –**4) 1.17**

**Directions (6 – 10): Study the given information carefully and answer the given questions:
An input-output is given in different steps. Some mathematical operations are done in each step. No mathematical operation is repeated in next step.**

**Find the addition of two numbers obtained in step III?**

1) 1.5

2) 3

3) 7

4) 3.5

5) None of these

###### Answer

Answer –**4) 3.5**

Solution:

In first step:

5 × 1 = 5, 3 × 2 = 6

1 × 3 = 3, 2 × 4 = 8

2 × 4 = 8, 2 × 4 = 8In second step:

Adding all the first digits: 5 + 3 + 8 = 16

Adding all the second digits: 6 + 8 + 8 = 22In third step:

1 + 6 = 7, 7/2 = 3.5

2 + 2 = 4, 4/2 = 2In fourth step:

3.5 – 2 = 1.5

**Find the sum of numbers obtained in 1st step?**

1) 232

2) 185

3) 188

4) 183.5

5) None of these
