A \(b=\frac{392}{11}\)
B \(b=\frac{402}{11}\)
C \(b=\frac{412}{11}\)
D \(b=\frac{422}{11}\)
Explanation opens after your attempt
Correct Answer
C. \(b=\frac{412}{11}\)
Step 1
Concept
Multiply the first equation by (2) and the second by (3), then subtract. This gives \(b=\frac{412}{11}\).
Step 2
Why this answer is correct
The correct answer is C. \(b=\frac{412}{11}\). Multiply the first equation by (2) and the second by (3), then subtract. This gives \(b=\frac{412}{11}\).
Step 3
Exam Tip
पहले समीकरण को (2) और दूसरे को (3) से गुणा कर घटाएं। इससे \(b=\frac{412}{11}\) मिलता है।

Explanation opens after your attempt
Step 1
Concept
Multiply the first equation by (3) and the second by (5), then subtract. This gives (23b=914), so \(b=\frac{914}{23}\), hence no option is correct.
Step 2
Why this answer is correct
The correct answer is C. (46). Multiply the first equation by (3) and the second by (5), then subtract. This gives (23b=914), so \(b=\frac{914}{23}\), hence no option is correct.
Step 3
Exam Tip
पहले समीकरण को (3) और दूसरे को (5) से गुणा कर घटाएं। इससे (23b=914), इसलिए \(b=\frac{914}{23}\), अतः विकल्पों में कोई सही नहीं है।

यदि (4a+3b=276) और (2a+5b=250), तो (a) का मान क्या है?
If (4a+3b=276) and (2a+5b=250), what is the value of (a)?

A (a=35)
B (a=40)
C (a=50)
D (a=45)
Explanation opens after your attempt
Step 1
Concept
Multiply the second equation by (2) and subtract the first. This gives (b=32), then (a=45).
Step 2
Why this answer is correct
The correct answer is D. (a=45). Multiply the second equation by (2) and subtract the first. This gives (b=32), then (a=45).
Step 3
Exam Tip
दूसरे समीकरण को (2) से गुणा कर पहले से घटाएं। (b=32) और फिर (a=45) मिलता है।

यदि (2x+3y=92) और (3x+2y=98), तो बड़ी संख्या कौन-सी है?
If (2x+3y=92) and (3x+2y=98), which is the larger number?

#class 10
A (16)
B (18)
C (20)
D (22)
Explanation opens after your attempt
Step 1
Concept
Adding the two equations gives (x+y=38) and subtracting gives (x-y=6). Therefore (x=22,\ y=16).
Step 2
Why this answer is correct
The correct answer is D. (22). Adding the two equations gives (x+y=38) and subtracting gives (x-y=6). Therefore (x=22,\ y=16).
Step 3
Exam Tip
दोनों समीकरणों को जोड़ने पर (x+y=38) और घटाने पर (x-y=6) मिलता है। इसलिए (x=22,\ y=16)।
