एक नाव शांत जल में (20) किलोमीटर प्रति घंटा चलती है। धारा की गति (x) है। (48) किलोमीटर धारा के साथ और (32) किलोमीटर धारा के विरुद्ध जाने में कुल (4) घंटे लगते हैं। (x) क्या है?

A boat moves at (20) kilometres per hour in still water. The stream speed is (x). It takes (4) hours to go (48) kilometres downstream and (32) kilometres upstream. What is (x)?

Explanation opens after your attempt
Correct Answer

A. (4)

Step 1

Concept

The equation is \(\frac{48}{20+x}+\frac{32}{20-x}=4\). Substituting (x=4) gives time (2+2=4) hours.

Step 2

Why this answer is correct

The correct answer is A. (4). The equation is \(\frac{48}{20+x}+\frac{32}{20-x}=4\). Substituting (x=4) gives time (2+2=4) hours.

Step 3

Exam Tip

समीकरण \(\frac{48}{20+x}+\frac{32}{20-x}=4\) है। (x=4) रखने पर समय (2+2=4) घंटे मिलता है।

एक व्यक्ति (300) किलोमीटर यात्रा करता है। गति (10) किलोमीटर प्रति घंटा कम करने पर समय (1) घंटा बढ़ जाता है। मूल गति क्या है?

A person travels (300) kilometres. If the speed is reduced by (10) kilometres per hour, the time increases by (1) hour. What is the original speed?

Explanation opens after your attempt
Correct Answer

A. (60)

Step 1

Concept

Let the original speed be (x), then \(\frac{300}{x-10}-\frac{300}{x}=1\). Solving gives (x=60).

Step 2

Why this answer is correct

The correct answer is A. (60). Let the original speed be (x), then \(\frac{300}{x-10}-\frac{300}{x}=1\). Solving gives (x=60).

Step 3

Exam Tip

मूल गति (x) हो, तो \(\frac{300}{x-10}-\frac{300}{x}=1\)। हल करने पर (x=60) मिलता है।
