An input-output is given in different steps. Some mathematical operations are done in each step. No mathematical operation is repeated in next step.
- What is the multiplication of all the numbers of step 2?
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
Answer – 4) 289
- 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?
