A. \(S = \frac{(5R - 47)}{4}\)

B. \(S = \frac{(4R + 47)}{5}\)

C. \(S = \frac{(5R + 17)}{4}\)

D. \(S = \frac{(4R - 17)}{5}\)

E. \(S = \frac{5R}{4} - 12\)

simplify given expression(R - 3)/28 = (S + 8)/35
we get
\(S = \frac{(5R - 47)}{4}\)
IMO A

E. \(S = \frac{5R}{4} - 12\)


\(\frac{(R - 3)}{28} = \frac{(S + 8)}{35}\)

Or, \(\frac{(R - 3)}{4} = \frac{(S + 8)}{5}\)

Or, \(5R - 15 = 4S + 32\)

Or, \(4S = 5R - 47\)

Or, \(S = \frac{5R - 47}{4}\), Answer must be (A)

As can also be seen from the answer choices, we need to express S in terms of R. Simplifying the equation, we have:

35(R-3) = 28(S+8)

35R - 105 = 28S + 224

35R - 329 = 28S

7(5R - 47)/28 = S

(5R - 47)/4 = S
