Correct Answer: 16

Solution : Let the bigger number be $x$ and the smaller number be $y$.
Given that $x-y=3951$-----------------(1)
Also, According to the question,
$x=y×12+13$
$⇒x-12y=13$-----------------------(2)
Subtracting equation (2) from equation (1), we get,
$11y=3938$
⇒ $y = 358$
So, $x=3951+358=4309$
$\therefore$ The sum of the digits of the larger number = 4 + 3 + 0 + 9 = 16
Hence, the correct answer is 16.

Correct Answer: Satisfy

Solution : The correct choice is the fourth option.

Annoy means to disturb or irritate someone, causing them to feel bothered or frustrated. Satisfy is the antonym because it means to fulfil or meet someone's needs or desires, leading to contentment or fulfilment rather than causing irritation or disturbance.

The meanings of the other options are as follows:

• Graze: This means to feed on growing grass, referring to animals feeding on pasture.
• Mystify: This means to perplex or bewilder someone, causing confusion or puzzlement by making something mysterious or difficult to understand.
• Employ: This means to use or engage in something, such as employing a tool or method for a particular purpose.

Correct Answer: 60

Solution : Given:
34 A 15 B 3 C 11 B 2 A (51 D 17) = ?

After replacing the letters with the mathematical signs, we get –
⇒ 34 + 15 × 3 – 11 × 2 + ( 51 ÷ 17)
⇒ 34 + 15 × 3 – 11 × 2 + 3
⇒ 34 + 45 – 22 + 3
= 60

Hence, the first option is correct.

Correct Answer: 60

Solution : Given: Ratio of two numbers is 3 : 4 and their HCF is 5.
Here, the common factor is 5.
So, the numbers will be 3 $\times$ 5 = 15 and 4 $\times$ 5 = 20
Now, 15 = 3 × 5 and 20 = 4 × 5
LCM = 3 × 4 × 5 = 60
Hence, the correct answer is 60.

Correct Answer: 36.27

Solution : Given: Length of the arc of a circle = 19 cm
Radius = 30 cm
We know that,
Length of the arc = $\frac{\theta}{360^\circ}\times 2 \pi r$
⇒ $19= \frac{\theta}{360^\circ}\times 2 \times\frac{22}{7}\times 30$
⇒ $\theta=\frac{19\times7 }{2\times 22\times 30}\times 360^\circ$
⇒ $\theta=36.27^\circ$
Hence, the correct answer is 36.27.

Correct Answer: 7

Solution : Given: The number 763254 is divisible by 18.
5 times of 41 from the number is subtracted = 763254 – 5 × 41 = 763254 – 205 = 763049
Now, Using divisibility rules:
For 2, if its last digit is even.
For 3, if the sum of its digits is divisible by 3 = 7 + 6 + 3 + 0 + 4 + 9 = 29
For 5, if its last digit is 0 or 5.
For 7, multiply the last digit by 2, and subtract it from the rest of the number; if the result is divisible by 7 = 76304 – 2 × 9 = 76304 – 18 = 76286, which is divisible by 7.
So, the number is divisible by 7.
Hence, the correct answer is 7.

Correct Answer: Rs. 12,320

Solution : Principal = Rs. 10,000
Rate at first year = 10%
Amount after 2 years= $P(1+\frac{R_1}{100})(1+\frac{R_2}{100})$ to solve this where $P$ is principal, $R_1$ and $R_2$ are the rates of interest per annum for two successive years.
$\therefore$ Amount after two years = $10000(1+\frac{10}{100})(1+\frac{12}{100})$ = 12,320
Hence, the correct answer is Rs. 12,320.
