Snehas weight is 140% of Veenas weight. Rinas weight is 90% of Sanas weight. Sana weighs twice as much as Veena. If Snehas weight is x% of Rinas weight, then x is equal to:

Let Veena's weight = 1 kg

Sana's weight = 2 kg

Sneha's weight = 1.4 kg

Rina's weight = 1.8 kg

Now,according to the given data in the question,

1.8x100 = 1.4

x = 1.4 × 1001.8 = 7009 = 77 79.
