Choose the best and correct alternatives.
Q-3) 841 : 29 : : 289 ?
Explanation:
As, 841 = (29)2
Similarly, 289 = (17)2.
Directions: In each of the following questions, there is a certain relationship between two given numbers on one side of (: :) and one number is given on another side of (: :) while another number is to be found the given alternatives, having the same relationship with this number as the number of the given pair bears. Choose the best and correct alternatives.
Q-4) 8 : 28 : : 27 : ?
Explanation:
$$\text"As, "\text"8 x 3 +4 is 28"$$
$$\text"similarly, "\text" 27 x 3 + 4 is 85".$$
Directions: In each of the following questions, there is a certain relationship between two given numbers on one side of (: :) and one number is given on another side of (: :) while another number is to be found the given alternatives, having the same relationship with this number as the number of the given pair bears. Choose the best and correct alternatives.
Q-5) 12 : 30 : : 18 : ?
Explanation:
$$\text"As, "\text"12 x 2 + 6 is 30"$$
$$\text"similarly, "\text" 18 x 2 + 6 is 42".$$
Directions: In each of the following questions, there is a certain relationship between two given numbers on one side of (: :) and one number is given on another side of (: :) while another number is to be found the given alternatives, having the same relationship with this number as the number of the given pair bears. Choose the best and correct alternatives.
Q-6) 5 : 100, 4 : 64 : : 4 : 80, 3 : ?
Explanation:
As, 5 x 20 = 100, 4 x 16 = 64
Similarly, 4 x 20 = 80 and 3 x 16 = 48
48 is the answer.
Directions: In each of the following questions, there is a certain relationship between two given numbers on one side of (: :) and one number is given on another side of (: :) while another number is to be found the given alternatives, having the same relationship with this number as the number of the given pair bears. Choose the best and correct alternatives.
Q-7) 149 : 238 : : 159 : ?
Explanation:
$$\text"The relationship is"$$ x : (x + 89).
As, $$\text"149":\text"149"+\text"89"=\text"149" :\text"238".$$
$$\text" Similarly",\text"159":\text"159"+\text"89"=\text"159" :\text"248"$$
Directions: In each of the following questions, there is a certain relationship between two given numbers on one side of (: :) and one number is given on another side of (: :) while another number is to be found the given alternatives, having the same relationship with this number as the number of the given pair bears. Choose the best and correct alternatives.
Q-8) 583 : 488 : : 293 : ?
Explanation:
As, Sum of digits of 583 = 5 + 8 + 3 = 16
and Sum of digits of 488 = 4 + 8 + 8
Similarly, Sum of digits of 293 = 2 + 9 + 3 = 14
and Sum of digits of "378" = 3 + 7 + 8 = 18
Here, difference of both sum of digits are (20 - 16) = (18 - 14) = 4.
Directions: Each of the following questions, choose one number which is similar to the numbers in the given set.
Q-9) Given set : 992, 733, 845, 632
Explanation:
In all the numbers, the middle digit is the sum of the digits of the product of other two digits.
Now, 9 × 2 = 18, 1+8 = 9 (middle digit in 992);
7 × 3 = 21, 2+1 = 3 (middle digit in 733);
8 × 5 = 40, 4+0 = 4 (middle digit in 845) and so on.
Directions: Each of the following questions, choose one number which is similar to the numbers in the given set.
Q-10) Given set : 363, 489, 579
Explanation:
| Numbers |
Sum of digits |
New sum of digits |
| 363 |
3+6+3 = 12 |
1+2 = 3 |
| 489 |
4+8+9 = 21 |
2+1 = 3 |
| 579 |
5+7+9 = 21 |
2+1 = 3 |
| 471 |
4+7+1 = 12 |
1+2 = 3 |
