Explanation

Let's calculate each option:

1/9 of 504 = 504 / 9 = 56

1/4 of 236 = 236 / 4 = 59

1/3 of 741 = 741 / 3 = 247

1/16 of 1028 = 1028 / 16 = 64.25

Comparing the results:

56, 59, 247, 64.25

The greatest number is 247, which corresponds to 1/3 of 741.

Explanation

"Owing to" means because of, and it is used to state the reason for something.

Correct sentence: Owing to illness, he could not attend the party.

Explanation

Given the pattern:

12 ∗ 21 = 9 = (2 - 1) × (2 + 1) = 1 × 3 = 3 doesn't fit, but (2 + 1)² = 3² = 9 fits

23 ∗ 32 = 25 = (3 - 2) × (3 + 2) = 1 × 5 = 5 doesn't fit, but (3 + 2)² = 5² = 25 fits

If the pattern is (last digit of first number + first digit of second number)²:

34 ∗ 43 = (4 + 4)² = 8² = 64 doesn't fit, but (4 + 3)² = 7² = 49 fits

Explanation

pH = –log [H⁺]

It measures the acidity or alkalinity of a solution based on the hydrogen ion concentration.

The pH scale ranges from 1 to 14, with:

• 1-6 being acidic
• 7 being neutral (neither acidic nor basic)
• 8-14 being basic (alkaline)

Explanation

Explanation

To find the number of handshakes, we can use the combination formula:

nC2 = n(n-1)/2

where n is the number of members (13).

For before the meeting: 13C2 = 13(12)/2 = 78

For after the meeting: 13C2 = 13(12)/2 = 78

Total handshakes = 78 + 78 = 156

Explanation

Let's denote the original price as x.

Given:

Discount = 30%

Sale price = Rs. 140

Formula:

Sale price = Original price - Discount

Sale price = x - (30% of x)

140 = x - 0.3x

140 = 0.7x

x = 140 / 0.7

x = 200

Explanation

Let's break it down:

Original price per kg = Rs. 200

Increased price per kg = 200 + (25% of 200) = 200 + 50 = Rs. 250

To keep expenditure the same, let's assume original consumption is 1 kg, and new consumption is x kg.

Original expenditure = 200 * 1 = Rs. 200

New expenditure = 250 * x = Rs. 200

x = 200 / 250 = 0.8 kg

Percentage decrease in consumption = ((1 - 0.8) / 1) * 100% = 20%

Explanation

The sum of the 5 numbers is:

5 × 23 = 115

The sum of the 4 numbers is:

4 × 25 = 100

The fifth number is:

115 - 100 = 15
