The cost of 4 rings and 2 bangles of gold is 40,000. What is the cost of 10 rings and 5 bangles?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. ₹1,00,000.
Let the cost of one gold ring be x, and the cost of one gold bangle be y
4x + 2y = 40000
⇒ 2.5(4x + 2y) = 2.5 × 40000
⇒ 10x + 5y = 100000
Hence, the cost of 10 rings and 5 bangles is ₹1,00,000.
