The ratio of money with Ram and Gopal is 7 : 17 and that with Gopal and Krishan is 7: 17. If Ram has Rs. 490, Krishan has ?

1. Rs. 2890
2. Rs. 2330
3. Rs. 1190
4. Rs. 2680

Correct Option: A

Ram : Gopal = 7 : 17 = 49 : 119
Gopal : Krishan = 7 : 17 = 119 : 289
∴ Ram : Gopal : Krishan = 49 : 119 : 289
⇒ Ram : Krishan = 49 : 289
Thus, 49 : 289 = 490 : N
&there N = 289 x 490 / 49
= Rs. 2890
