The ratio of money with Jack and John is 7 : 13, and that with John and Jonas is 9 : 11. If Jack has Rs 6,300, then how much money does Jonas have?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Rs 14,300.
Calculations:
Ratio of Jack and John = 7/13 = (7 × 9)/(13 × 9) = 63/117
Ratio of John and Jonas = 9/11 = (9 × 13)/(11 × 13) = 117/143
Ratio (Jack : John : Jonas) = 63 : 117 : 143
Let the amount of money Jack has be 63x
According to the question;
⇒ 63x = 6300
⇒ x = 100
Money with Jonas = (143 × 100) = Rs. 14,300
