Explanation opens after your attempt
Correct Answer

C. (480)

Step 1

Concept

(S_{20}=202+4(20)=480). In such a question, there is no need to find (a) and (d) separately.

Step 2

Why this answer is correct

The correct answer is C. (480). (S_{20}=202+4(20)=480). In such a question, there is no need to find (a) and (d) separately.

Step 3

Exam Tip

(S_{20}=202+4(20)=480)। ऐसे प्रश्न में अलग से (a) और (d) निकालने की जरूरत नहीं है।

Question 2/4 Hard Mathematics Pair of Linear Equations in Two Variables Algebraic methods: Substitution method and Elimination method. Class 10 Level 57

यदि \(\frac{x+y}{3}=7\) और \(\frac{x-y}{4}=2\), तो (x-y) का मान क्या है?

If \(\frac{x+y}{3}=7\) and \(\frac{x-y}{4}=2\), what is the value of (x-y)?

Explanation opens after your attempt
Correct Answer

C. (8)

Step 1

Concept

The second equation directly gives (x-y=8). In exams, the asked expression is sometimes obtained directly.

Step 2

Why this answer is correct

The correct answer is C. (8). The second equation directly gives (x-y=8). In exams, the asked expression is sometimes obtained directly.

Step 3

Exam Tip

दूसरा समीकरण सीधे (x-y=8) देता है। परीक्षा में कभी-कभी पूछे गए व्यंजक का मान सीधे मिल जाता है।

Question 3/4 Easy Mathematics Pair of Linear Equations in Two Variables Algebraic methods: Substitution method and Elimination method. Class 10 Level 55

समीकरणों (x+y=15) और (y=6) से (x) कितना होगा?

From (x+y=15) and (y=6), what is (x)?

Explanation opens after your attempt
Correct Answer

C. (x=9)

Step 1

Concept

Putting (y=6) gives (x+6=15), so (x=9). Check the final answer even in simple equations.

Step 2

Why this answer is correct

The correct answer is C. (x=9). Putting (y=6) gives (x+6=15), so (x=9). Check the final answer even in simple equations.

Step 3

Exam Tip

(y=6) रखने पर (x+6=15), इसलिए (x=9)। सरल समीकरणों में भी अंतिम उत्तर जांचें।

Question 4/4 Easy Mathematics Pair of Linear Equations in Two Variables Algebraic methods: Substitution method and Elimination method. Class 10 Level 55

यदि (x+y=12) और (x=7), तो (y) का मान क्या है?

If (x+y=12) and (x=7), what is the value of (y)?

Explanation opens after your attempt
Correct Answer

C. (y=5)

Step 1

Concept

Putting (x=7) gives (7+y=12), so (y=5). Use the given variable value directly.

Step 2

Why this answer is correct

The correct answer is C. (y=5). Putting (x=7) gives (7+y=12), so (y=5). Use the given variable value directly.

Step 3

Exam Tip

(x=7) रखने पर (7+y=12), इसलिए (y=5)। दिए हुए चर का मान सीधे प्रयोग करें।
