Correct Answer

B. (448)

Step 1

Concept

In this AP, (a=105), (d=7), so \(a_{50}=105+49\times7=448\). In an AP of multiples, choose the first correct multiple.

Step 2

Why this answer is correct

The correct answer is B. (448). In this AP, (a=105), (d=7), so \(a_{50}=105+49\times7=448\). In an AP of multiples, choose the first correct multiple.

Step 3

Exam Tip

इस AP में (a=105), (d=7), इसलिए \(a_{50}=105+49\times7=448\)। गुणजों की AP में पहला सही गुणज चुनें।

अनुक्रम \(81,72,63,54,\ldots\) का सामान्य अंतर क्या है?

What is the common difference of \(81,72,63,54,\ldots\)?

Explanation opens after your attempt
Correct Answer

B. (-9)

Step 1

Concept

Each step subtracts (9), so (d=-9). In exams, keep the difference negative for descending order.

Step 2

Why this answer is correct

The correct answer is B. (-9). Each step subtracts (9), so (d=-9). In exams, keep the difference negative for descending order.

Step 3

Exam Tip

हर कदम पर (9) घट रहा है, इसलिए (d=-9)। परीक्षा में अवरोही क्रम में अंतर ऋणात्मक रखें।

(3) के दो क्रमागत धनात्मक गुणजों का गुणनफल (270) है। वे गुणज कौन से हैं?

The product of two consecutive positive multiples of (3) is (270). Which multiples are they?

Explanation opens after your attempt
Correct Answer

C. (15) और (18)(15) and (18)

Step 1

Concept

Let the multiples be (x) and (x+3). From (x(x+3)=270), we get (x=15).

Step 2

Why this answer is correct

The correct answer is C. (15) और (18) / (15) and (18). Let the multiples be (x) and (x+3). From (x(x+3)=270), we get (x=15).

Step 3

Exam Tip

गुणज (x) और (x+3) मानें। (x(x+3)=270) से (x=15) मिलता है।
