Three numbers are in the ratio of 1 : 2 : 3. The product of the three numbers is 1296. What is the sum of the three numbers?
Answer & explanation
Correct answer: option 1
Here,
A : B : C = 1 : 2 : 3
⇒ Product of A, B and C = 1296
⇒ \( {6x }^{3 } \) = 1296
⇒ \( {x }^{3 } \) = 216
⇒ x = 6,
⇒ Sum of A + B + C = 1 + 2 + 3 = 6 x 6 = 36.
