Explanation

• 35 + 13 = 48

• 48 + 15 = 63

• 63 + 17 = 80

• 80 + 19 = 99

Rule: Add consecutive odd numbers: 13, 15, 17, 19.

Explanation

15% of 15% of 32,000

Step 1: Find 15% of 32,000.

15/100×32000=4800

Step 2: Find 15% of 4,800.

15/100×4800=720

Explanation

If 20% of a = 80% of b

Then:

0.2 x a = 0.8 x b

a = 0.8 / 0.2 x b

a = 4b

So:

a + b = 4b + b = 5b

And in terms of a:

a + b = a + a/4 = 5a/4 = 1.25a

Explanation

2 + 3 = 5

5 + 7 = 12

12 + 11 = 23

23 + 15 = 38

38 + 19 = 57

57 + 23 = 80

Explanation

Series: 13, 32, 24, 43, 35, ?, 46, 65, 57, 76

Notice the pattern alternates:

+19, −8, +19, −8, +19, −8, +19, −8, +19

So:

35 + 19 = 54

Then 54 − 8 = 46, which matches.

Explanation

Divide the numerator by the denominator. 

3 ÷ 4 = 0.75

Explanation

Pattern:

18 + 12 = 30

30 + 12 = 42

42 + 12 = 54

54 + 12 = 66

Logic: Add 12 to each number.

Explanation

If 13% of a number is 52, then:

Number = 52 ÷ 13 × 100 = 400

Explanation

Loss = 9,000 − 8,000 = 1,000

Loss % = (Loss ÷ Cost Price) × 100

= (1,000 ÷ 9,000) × 100

= 11.11%

Explanation

Given:

• Price = Rs. 250
• Old sales tax = 8%
• New sales tax = 6%

Step 1: Difference in tax rate
8% − 6% = 2%

Step 2: Calculate 2% of Rs. 250

2/100x250 =5

$$frac{2}{100} times 250 = 5$$

Rs. 5
