Question

From the following table, find the values of a, b and c: Number of men 130 70 b 120 Number of daysrequired to dothe same work a 39 30 c

KnowledgeBoat · Accepted Answer

It is a case of inverse variation: ∴ 130 x a = 70 x 39 = b x 30 = 120 x c Taking, 130 x a = 70 x 39 ⇒ a = ⇒ a = 7 x 3 ⇒ a = 21 Taking, 70 x 39 = b x 30 ⇒ b = ⇒ b = 7 x 13 ⇒ b = 91 Taking, 70 x 39 = 120 x c ⇒ c = ⇒ c = 22.75 Hence, the value of a = 21, b = 91 and c = 22.75
