Question

Farmer Tan harvested some apples, pears and oranges for sale at the market.
1/10 of the fruits were apples. The number of pears was twice the number of oranges. There were 85 more pears than apples.

How many fruits were there altogether ?

Answer

10 – 1 = 9 (pears and oranges)
9/3 = 3 (oranges)
3 x 2 = 6 (pears)
6 – 1 = 5 (pears more than apples)
85/5 = 17
17 x 10 = 170

Ans : 170 fruits.

guess this is a grouping type question , actually  i was stuck to use ” number of pears was twice the number of oranges ” to 1 group is 3 units. now i understood like this

1 pear = 2 units

1 orange = 1 units

1 group = 3 units .

total 3 groups

1  * 3  = 3 oranges

2 * 3 = 6 pears.

apple = 1 units

difference : pears – apples = 6 – 1 = 5

85 / 5 = 17

10 units = 17 * 10 = 170

I would rather do it as follows :

total number of fruits : 10 units

number of apples : 1 unit

10 units – 1 unit = 9 (units)

2 + 1 = 3

9 units / 3 = 3 units (number of oranges)

9 units – 3 units = 6 units (number of pears)

6 units – 1 units = 5 units = 85

10 units = 170

Ans : 170 fruits.

This is a Branching question. 

   Apple Pear  Orange Total
R1   1u 9u 10u
R2   2 1 3
CR 3u 18u 9u 30u

18u – 3u = 85

15u = 85

30u = 85 × 2 = 170 fruits
