समुच्चय \(C={x:x\in N, x\) (14) और (35) के बीच (7) का गुणज है(}) कौन-सा है?

Which set is \(C={x:x\in N, x\) is a multiple of (7) between (14) and (35})?

Explanation opens after your attempt
Correct Answer

B. \(C=\{21,28\}\)

Step 1

Concept

The word between usually excludes the endpoints (14) and (35).

Step 2

Why this answer is correct

The multiples of (7) inside are (21) and (28).

Step 3

Exam Tip

In between-type questions, do not include endpoints automatically. चरण 1: बीच शब्द सामान्यतः सिरों (14) और (35) को छोड़ता है। चरण 2: अंदर आने वाले (7) के गुणज (21) और (28) हैं। चरण 3: बीच वाले प्रश्न में सिरों को तुरंत शामिल न करें।
