Reasoning Input Output based on SBI PO Mains
Directions (1
– 5): Study the following information carefully and answer the given questions.
A number arrangement machine arranges two digit numbers in typical manner. The first step has been obtained by multiplying the digits in input. Multiplication has not been done in any other steps. They are obtained by applying certain logic. Each step is a resultant of previous step.

Solutions:
(1 – 5):
In step I: 7* 5 = 35; 3*2 = 6;
5* 8 = 40; 6*1 = 6;
4* 7 = 28; 9*1 = 9;
In step II: each first digit and third digit of the numbers are added
and then subtracted with second digit.
(6 + 3) - 5 = 4; (6 + 4)
- 0 = 10; (2+9) – 8 = 3;
In step III: divide the second number by the first number and also third
number by second number.
10/4 = 2.5; 3/10=0.3;
In step IV: subtract the second number from first number. This is the
final output.
2.5– 0.3 = 2.2
1. B) 5/2
+ 0/2 + 8/2 = 2.5 + 0 + 4= 6.5
2. C)
3. D) The
first digit of the third number in step I is ‘2’ and the second digit of the
first number is ‘5’. Hence, (2, 5)
4. A) The
third digit of the third number in step I is ‘9’ and second digit of the first
number in step I is ‘5’. Hence, 9 – 5 =4
5. B) The
two numbers obtained in step II are 4, 10 and 3. Hence, 4 *10*3 = 120
(6 – 10):
In step I: 1* 7 = 7; 4*2 = 8;
3* 3 = 9; 9*1 = 9;
2* 2 = 4; 1*6 = 6;
In step II: each first digits of three numbers are added and multiplied
by two and each second digits also do same.
7 + 9 + 4 = 20* 2 = 40; 8
+ 9 + 6 = 23*2 = 46;
In step III: divide the second digit by first digit in each two numbers.
0/4 = 0; 6/4=1.5;
In step IV: subtract the second number from first number. This is the
final output.
0 – 1.5 = -1.5
6. B) 4/2 + 0/2 + 4/2 + 6/2 = 2 + 0 + 2 + 3
= 7
7. C) The
final output is ‘ -1.5’ = -1.5 – 7.5 = - 9.0
8. D) The
first digit of the third number in step I is ‘4’ and the second digit of the
first number is ‘8’. Hence, (4, 8)
9. A) The
first digit of the second number in step II is ‘4’ and second digit of the
first number in step II is ‘0’. Hence, 4 – 0 =4
10. D) The
two numbers obtained in step III are 0 and 1.5. Hence, 0 * 1.5 = 0
