number to get=26.5
number to be added=?
so,first add=13.37+8.031=21.401
26.5-21.401
so, the number needed to be added=5.099
2.the weight of sugar =2kg 500g
the weight of flour =1kg 200g
the weight of rice. =5 kg 800g
add the weight of sugar,flour and rice
2.500+1.200+5.800=9.95
so,the total weight of purchase=9.95kg
3.distance between two villages=8km
distance travelled by bike=3km350m
distance travelled by bicycle=2km580m
distance travelled by walking =?
add the distance travelled by bike and bicycle =3.350+2.580=5.93km
now subtract 5.93km from 8 km
8-5.93=2.07
the distance travelled by walking=2.07km
4.cost of pen=8.75
cost of pencil=3.26
cost of note book=10.85
rupees given to shopkeeper=50
amount given back by shopkeeper=?
add the cost of pen,pencil and note book
8.75+3.25+10.85=22.85
now subtract 22.85 from 50
50-22.85=27.15
so the amount given by shopkeeper=₹27.15
5.cost of 1 litre petrol=76.62
cost of 1 litre kerosene=38.25
difference between their cost is 76.62-38.25=38.37
so the petrol is ₹38.37 more than kerosene
