Question1.
Orange ----- 3 units
Pear --------- 4 units
Lemon ------ 1.5 x 4 = 6 units

Difference between lemon and orange,
6 units - 3 units = 3 units
3 unis -------- 15 pcs
1 unit --------- 15 / 3 = 5 pcs
pear 4 units ----- 5 x 4 = 20 pcs (answer)

Question 2
2 units of girls = 3 units of boys
1 unit of girl = 1.5 unit of boys

Convert 3 units of girls in terms of unit of boys

Total Girls ----- 3 units of girls x 1.5 = 4.5 units of boys
Total Boys -----11 units of boys
Difference ------ 11 - 4.5 =6.5 units
Total boys + girls = 4.5 + 11 = 15.5 units

15.5 units ------- 186
1 unit ------------- 186 / 15.5 =12
difference ------- 6.5 units x 12 =78 pupils ( answer)
