Correct Answer:
D: 3: 1
Explanation:
A man takes twice as long to row a distance against the stream as to row the same distance in favor of the stream . The ratio of the speed of the boat (in still water ) and the stream is : Correct Answer 3: 1 Let , Distance = x we know, Down stream = Boat + Stream Up stream = Boat - stream ATQ, 2xBoat + stream = xBoat - Stream⇒2x (Boat - Stream) = x(Boat + Stream ) ⇒2Boat - 2 Stream = Boat + Stream ⇒2 Boat - Boat = 2 Bstream + Stream⇒Boat = 3 Stream ⇒BoatStream = 3.'.Boat : Stream = 3 : 1
For any two numbers m, n; (m+n) : (m-n): mn=7 :1 : 60. Find the value of 1/m : 1/n
Correct Answer:
C: 3 :4
Explanation:
For any two numbers m, n; (m+n) : (m-n): mn=7 :1 : 60. Find the value of 1/m : 1/n Correct Answer 3 :4 Given , (m + n) (m - n) : mn = 7 :1 : 60 ∴ (m + n) (m - n) = 7 :1 ⇒m + nm - n = 71⇒m + n + m - nm + n - m + n = 7 + 17 - 1⇒2m2n = 86⇒mn = 43⇒nm = 34⇒m1n = 34.'. 1m : 1n = 3 : 4

Correct Answer:
A: 2 : 1 : 3
Explanation:
A, B and C investment in a partnership in the ratio of 5 : 6 : 8. The ratio of their profit is 5 : 3 : 12. Find the ratio of time for their investment ? Correct Answer 2 : 1 : 3 Let , A = 5x B = 6y C = 8z We know , 5x: 6y:8z = 5:3 : 12 ∴ 5x : 6y = 5: 3 ⇒5x9y = 53⇒xy = 5×63×5⇒xy = 21.'. x :y = 2 : 1.'. x : y : z = 2: 1 : 3 6y : 8z = 3 :12 ⇒6y8z = 312⇒yz = 3×86×12⇒yz = 13.'. y : z = 1: 3
