Number of trees that can be planted on one side of road = (Length of road/gap between two trees ) + 1
Number of trees that can be planted on one side of road = ( 1760/20 )+ 1Correct Option: D
Number of trees that can be planted on one side of road = (Length of road/gap between two trees ) + 1
Number of trees that can be planted on one side of road = ( 1760/20 )+ 1
Number of trees that can be planted on one side of road = 88 + 1 = 89
∴ Threes on the both sides
= 2 x 89 = 178

Divisor = 5 x 46 = 230
Also, 10 x Quotient = 230
∴ Quotient = 23
We know that
Dividend = (Divisor x Quotient ) + RemainderCorrect Option: C
Divisor = 5 x 46 = 230
Also, 10 x Quotient = 230
∴ Quotient = 23
We know that
Dividend = (Divisor x Quotient ) + Remainder
∴ Dividend = (230 x 23) + 46
∴ Dividend = 5290 + 46 = 5336
