Explanation
When you add 1/3 + 1/3, you are essentially combining two equal parts of a whole.
Since both fractions have the same denominator (3), you can simply add the numerators:
1/3 + 1/3 = (1 + 1)/3 = 2/3
So, the result is 2/3.

Explanation
The sequence is formed by adding consecutive terms that are three times larger than the previous gap.
2 + 2 = 4 (gap of 2)
4 + 6 = 10 (gap of 6, which is 3 times 2)
10 + 18 = 28 (gap of 18, which is 3 times 6)
28 + 54 = 82 (gap of 54, which is 3 times 18)

Explanation
The pattern of the sequence is obtained by adding 2, then 4, then 8, then 16, and so on (doubling the previous addition).Therefore, the next number in the sequence would be:
1 + 2 = 3
3 + 4 = 7
7 + 8 = 15
15 + 16 = 31
31 + 32 = 63
63 + 64 = 127
So, the correct answer is: 127

Explanation
(4 x 3 + 5 x 6) / (18 x 2 – 22)
= (12 + 30) / (36 - 22)
= 42 / 14
= 3

Explanation
√6 × √6 = √(6 × 6) (using the property of square roots)
= √36
= 6 (since 6^2 = 36)

- 20
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
If the result is 15, and we subtract 9 from it, we get:
15 - 9 = 6
Since we divided the number by 4, we multiply 6 by 4 to get:
6 × 4 = 24
- 30
- 35
- 40
- 45
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The pattern in the given equations is:
4 = 4 × 2 = 8
5 = 5 × 3 = 15
6 = 6 × 4 = 24
Following this pattern, we get:
7 = 7 × 5 = 35
So, the correct answer is: 35
