S varies directly as (R + 7), and S = 42 when R = 17.
Formula used:
S = k × (R + 7)
Where, k is the constant of proportionality
Calculations:
42 = k × (17 + 7)
⇒ 42 = k × 24
⇒ k = 42 / 24
⇒ k = 1.75
Now, find S when R = 29:
S = 1.75 × (29 + 7)
⇒ S = 1.75 × 36
⇒ S = 63
∴ The correct answer is option (2).
