Answer 1

(c) ₹480

Step-by-step explanation:

C and D's share are in the ratio of 2 1/4:1 3/4 = 9/4:7/4

Let x be C's share

$\frac{ \frac{9}{4} }{ \frac{7}{4} } = \frac{x}{210}$

$\frac{9}{4} \times \frac{4}{7} = \frac{x}{210}$

$\frac{9}{7} \times 210 = x$

$x = 270$

Total sum of money = ₹270 + ₹210 = ₹480

Hence, option (c) is the correct one
