The logic followed here is :

Second number = (First number)² - (First number)

For 18 : 306,

18² -18 = 324 -18 = 306.

Similarly,

For 19 : ?,

19² - 19 = 361 - 19 = 342.

Hence, the correct answer is "342".

Volt is the S.I. unit of potential difference.

Watt is the S.I. unit of power.

Ohm is the S.I. unit of resistance.

While an Ammeter is an instrument that measures current.

Hence, Ammeter is the correct answer.

The diagram below shows the path followed by Niharika:

So, the distance from her home to her final point = AC = AB + BC = 10 + 5 = 15km and her final point is in East direction.

Hence, "15km East" is the correct answer.

The logic is:

17 $ 22 = (1 + 7) - (2 + 2) = 8 - 4 = 4

56 $ 13 = (5 + 6) - (1 + 3) = 11 - 4 = 7

Similarly,

71 $ 25 = (7 + 1) - (2 + 5) = 8 - 7 = 1

Hence, '1' is the correct answer.

The Logic here is as follows:

Earthquakes, Volcanos, and Tsunami are types of Natural disasters.

Whereas, Global warming is not a part of a Natural disaster and is caused by climate change.

Hence, the correct answer is "Global Warming".

Given:

A can complete a work in 15 days

B can complete the work in 10 days

Calculation:

A's 1 day's work = 1/15

B's 1 day's work = 1/10

(A + B)'s 1 days work = 1/15 + 1/10 = 1/6

(A + B)'s 4 days work = 4/6 = 2/3

Remaining work after 4 days = 1 - 2/3 = 1/3

Remaining work completed by C in = 10 - 4 = 6 days

C's 1 days work = 1/3 × 1/6 = 1/18

∴ C alone can complete the work in 18 days.

Alternate Method

Let the total work be the LCM of (15, 10) i.e 30 units

So the efficiency of A = 30/15 = 2 units/day

And the efficiency of B = 30/10 = 3 units/day

A and B work for 4 days and will complete work = (3 + 2) × 4 = 20 units

Remaining work = 30 - 20 = 10 units

This work will be done by C in days = 10 - 4 = 6 days

So the efficiency of C = 10/6 = 5/3

∴ Total time taken by C to complete whole work = 30/(5/3) = 18 days

Calculation:

Alternate Method

Each term is in the form

⇒ for the fourth term n = 4

⇒ The fourth term should be

The series will become

⇒

⇒ 1/4 x (1/4 - 1/20)

⇒ 1/4 x 4/20

⇒ 1/20

∴ The required sum of the first four terms of the series is 1/20.

Given

A and B lent Rs.2787 at 15% compound interest, compounded annually. The amount A gets at the end of 3 years is same as B gets at the end of 5 years

Concept used

Amount = Principal (1 + R/100)ⁿ

Calculation

Let A and B lent P and P' amount

As per the question

P + P' = 2787

P (1 + 3/20)³ = P'(1 + 3/20)⁵

P/P′ = (1 + 3/20)²

P/P′ = (23/20)²

P/P′ = 529/400

529x + 400x = 2787

929x = 2787

x = 3

A lent 529 × 3 = Rs.1587

Given:

Average price of 16 books = Rs. 18

Average price of 14 books = Rs. 16.50

Price of one of remaining book = 50% of price of another remaining book

Concept used:

Average = Total sum of observation/Number of observations

Calculation:

As we know that

Average = Total sum of observation/Number of observations

Total price of 16 books = Rs. 18 × 16

⇒ Rs. 288

Total price of 14 books = Rs. 16.50 × 14

⇒ Rs. 231

Total Price of remaining books = Total price of 16 books - Total price of 14 books

⇒ Rs. (288 - 231)

⇒ Rs. 57

Now, Let the price of one of remaining book be x

Price of another remaining book = 50% of x

⇒ x/2

According to the question

x + (x/2) = Rs. 57

⇒ 3x/2 = 57

⇒ x = (57 × 2)/3

⇒ x = Rs. 38

Price of another remaining book = 38/2

⇒ Rs. 19

∴ The prices of books are Rs. 19 and Rs. 38.

Given

Principal = Rs. 4000

Time = 2 years

Formula Used

Simple Interest = (principal × rate × interest)/100

Amount = Principal(1 + R/100)^t

Amount = Principal + interest

Calculation

From 1st condition,

Simple Interest = (Principal × rate × interest)/100

⇒ Simple interest = (4000 × 12 × 2)/100

⇒ Simple Interest = 40 × 24 = Rs. 960

from 2nd condition

⇒ Amount = 4000(1 + 15/100)²

⇒ Amount = 4000 × (23/20) × (23/20)

⇒ Amount = Rs. 5290

Interest from 2nd condition = 5290 – 4000 = Rs. 1290

Himanshu gained = Rs. 1290 – Rs. 960 = Rs. 330

∴ Himanshu's gain in whole transaction is Rs. 330

‘मन चंगा तो कठौती में गंगा’, मिश्र वाक्य है। अतः इसका सही उत्तर विकल्प 3 होगा। अन्य विकल्प सही नहीं हैं।

Key Points

• The error lies in Part (b) of the sentence.
• 'Eyes' is a noun but in this sentence, it is qualifying the word 'surgery'.
• Therefore, in this sentence, 'eyes' is used as an adjective.
• When a noun is used as an adjective, it is used in the singular form.
  • Example: They are going for laser eye surgery.
• Therefore, the use of 'eyes' in Part (b) of the sentence should be replaced by 'eye' to make it grammatically correct.
• Hence, the correct answer is '(b)'.

Correct sentence: I'd rather have laser eye surgery go wrong.​​

Key Points​

• It can be inferred that the person was Thomas Hall.

The correct answer is option 1.

• The following is stated in the passage- "Thus, when Hofmann made some passing comments about the desirability of a synthetic substitute for quinine, it was unsurprising that his star pupil was moved to take up the challenge."
