#ap
#number-of-terms
#expert
A (15)
B (17)
C (19)
D (21)
Explanation opens after your attempt
Step 1
Concept
From (901=\frac{n}{2}(3+103)), (n=17). Exam tip: when first and last terms are known, use (S_n=\frac{n}{2}(a+l)).
Step 2
Why this answer is correct
The correct answer is B. (17). From (901=\frac{n}{2}(3+103)), (n=17). Exam tip: when first and last terms are known, use (S_n=\frac{n}{2}(a+l)).
Step 3
Exam Tip
(901=\frac{n}{2}(3+103)) से (n=17) है। परीक्षा में प्रथम और अंतिम पद मिलें तो (S_n=\frac{n}{2}(a+l)) लगाएं।

यदि किसी समान्तर श्रेणी में \(a_7=31\) और \(a_{19}=103\) है तो \(a_{34}\) का मान क्या होगा?
If in an AP \(a_7=31\) and \(a_{19}=103\), what is the value of \(a_{34}\)?
#ap-nth-term-hard
A (187)
B (193)
C (199)
D (205)
Explanation opens after your attempt
Step 1
Concept
\(d=\frac{103-31}{19-7}=6\), so \(a_{34}=103+15\times6=193\). First find (d), then move forward from the nearer term.
Step 2
Why this answer is correct
The correct answer is B. (193). \(d=\frac{103-31}{19-7}=6\), so \(a_{34}=103+15\times6=193\). First find (d), then move forward from the nearer term.
Step 3
Exam Tip
\(d=\frac{103-31}{19-7}=6\) इसलिए \(a_{34}=103+15\times6=193\)। पहले (d) निकालकर निकट पद से आगे बढ़ें।

यदि \(a_8=47\) और \(a_{15}=103\) है तो \(a_{22}\) क्या होगा?
If \(a_8=47\) and \(a_{15}=103\), what is \(a_{22}\)?
#ap two-known-terms nth-term class10
A (151)
B (155)
C (159)
D (163)
Explanation opens after your attempt
Step 1
Concept
\(d=\frac{103-47}{15-8}=8\) so \(a_{22}=103+7\times8=159\). Add equal term gaps for equally spaced positions.
Step 2
Why this answer is correct
The correct answer is C. (159). \(d=\frac{103-47}{15-8}=8\) so \(a_{22}=103+7\times8=159\). Add equal term gaps for equally spaced positions.
Step 3
Exam Tip
\(d=\frac{103-47}{15-8}=8\) इसलिए \(a_{22}=103+7\times8=159\)। बराबर दूरी वाले पदों में समान अंतर जोड़ें।

From (103=5+(n-1)7), (98=7(n-1)), so (n=15). When finding the term number, remember to add (1) at the end.
Step 2
Why this answer is correct
The correct answer is C. (15). From (103=5+(n-1)7), (98=7(n-1)), so (n=15). When finding the term number, remember to add (1) at the end.
Step 3
Exam Tip
(103=5+(n-1)7) से (98=7(n-1)), अतः (n=15)। पद संख्या निकालते समय अंत में (1) जोड़ना न भूलें।

समीकरणों (px+9y=45) और (20x+30y=103) का कोई हल न होने के लिए (p) का मान क्या होगा?
What is the value of (p) for the equations (px+9y=45) and (20x+30y=103) to have no solution?

B (6)
C (7)
D (8)
Explanation opens after your attempt
Step 1
Concept
For no solution, (p/20=9/30) and (45/103) must be different. This gives (p=6).
Step 2
Why this answer is correct
The correct answer is B. (6). For no solution, (p/20=9/30) and (45/103) must be different. This gives (p=6).
Step 3
Exam Tip
कोई हल नहीं के लिए (p/20=9/30) और (45/103) अलग होना चाहिए। इससे (p=6) मिलता है।

यदि (a=59q+44), तो (a-103) को 59 से भाग देने पर शेषफल क्या होगा?
If (a=59q+44), what is the remainder when (a-103) is divided by 59?
#euclids-division-lemma
#remainder-subtraction
#expert
A 0
B 1
C 58
D 44
Explanation opens after your attempt
Step 1
Concept
(a-103=59q+44-103=59q-59).
Step 2
Why this answer is correct
This can be written as (59(q-1)+0).
Step 3
Exam Tip
Therefore, the number is exactly divisible by 59 and the remainder is 0. चरण 1: (a-103=59q+44-103=59q-59)। चरण 2: इसे (59(q-1)+0) लिखा जा सकता है। चरण 3: इसलिए संख्या 59 से पूर्णतः विभाजित है और शेषफल 0 है।
