Clearty, 0.36 < 0.545 < 0.62 < 0.78 < 0.9
i. e.

5. (3) Let the number be x.
According to the question,
5
x
= 62 Þ x = 62 × 5 = 310
73% of 310 =
73
100
× 310 = 226.3
6. (4) 265 × 348 = 92220
7. (5) Let the five consecutive even number be x, x + 2 x + 4
x + 6 and x + 8 respectively.
According to the question,
x + x + 6 = 162
Þ 2x = 162 – 6 = 156
Þ x =
156
2
= 78
Sum of all numbers
= 78 + 80 + 82 + 84 + 86 = 410
8. (5) Let the number be x and y.
Accoding to the question,
2x + 3y = 36 ...(i)
3x + 2y = 39 ...(ii)
By equastion (i) × 3 – (ii) × 2,
6x + 9y – 6x – 4y = 108 – 78
Þ 5y = 30 Þ y =
30
5
= 6
From equation (i), we have,
2x + 3 × 6 = 36
Þ 2x = 36 – 18 = 18 Þ x =
18
2
= 9
The smaller number = 6
9. (3) Let the number be x and y.
Accoding to the question,
x + y – (x – y) = 42
Þ 2y = 42 Þ y =
42
2
= 21
x =
1092
21
= 52
10. (2) 81 × 81 = 6561
82 × 82 = 6724
To make 6659 a perfect square the number to be
added = 6724 – 6659 = 65
11. (1) Total number of candles
= 7 × 12 × 14 = 1176
12. (4) Let the two digit number be = 10 x + y where x > y
Accoding to the question,
x + y = 12 and x – y = 6
Adding these equations,
12
6
2 18
+ =
- =
=
x y
x y
x
Þ x =
18
2
= 9
y = 12 – 9 = 3
Number = 93
Again, let the number be 10x + y where x < y.
Then, x + y = 12 and y – x = 6
Adding these equations,
2y = 18 Þ y =
18
2
= 9
From equation (i),
x = 3
Number = 39
Thus we get two numbers. This does not satisfy the
uniqueness of answer.
