Prithvi has pears and peaches in the ratio of 10:13. Celine has pears and peaches in the ratio of 7:9. Vikram has pears and peaches in the ratio of 5:7. Who has a greater ratio of pears to peaches?

Correct option is D

For Prithvi: $$\frac{10}{13}$$​​

For Celine: $$\frac{7}{9}$$​​

For Vikram: $$\frac{5}{7}​$$​​

The least common multiple of 13, 9, and 7 is 819.

For Prithvi: $$\frac{10}{13} \times\frac{ 63}{63} = \frac{630}{819}$$​​

For Celine: $$\frac{7}{9} \times\frac{ 91}{91} = \frac{637}{819}$$​​

For Vikram: $$\frac{5}{7​} \times \frac{ 117}{117} =\frac{ 585}{819}$$​​
