1. If a Rope is 10m long two pieces of lengths 8/5m and 23/10m are cut off. What is the length of the rope left?
Solution:
Given Total Rope Length = 10m
Two pieces of lengths cut off are 8/5m and 23/10m
Therefore, to determine the rope left we need to subtract two pieces cut off i.e.
= 10 – 8/5 – 23/10
= 10-1.6-2.3
= 6.1m
Therefore, 6.1m of Rope is left.
2. A drum having paddy weights 240Kg whereas the weight of the empty drum is 50/4kg. Find the Weight of the Paddy within the drum?
Solution:
Weight of Drum and Paddy = 240Kg
Weight of Drum = 50/4Kg
Weight of Paddy = Weight of Drum and Paddy – Weight of Drum
= 240- 50/4
= 240 -12.5
= 227.5kg
The Weight of Paddy is 227.5 Kg.
3. A basket contains three types of Vegetables including 48/3kg all together. If 15/2 kg is carrot, 19/6kg is tomatoes and the rest are brinjal. What is the Weight of Brinjal?
Solution:
Total weight of three vegetables = 48/3 Kg
Weight of Carrot + Weight of Tomatoes + Weight of Brinjal = 48/3
15/2+19/6+ Weight of Brinjal = 48/3
Weight of Brinjal = 48/3-15/2-19/6
= (96-45-19)/6
= 32/6
= 16/3 Kg
Therefore, the Weight of Brinjal = 16/3 Kg.
4. Find the Cost of 7/5m of cloth if the cost of the cloth is $120/3 per m?
Solution:
Cost of 7/5m of Cloth = 7/5*(120/3)
=7/5*40
= $56
5. A truck moves at an Average Speed of 180/4 Km/hr. How much distance will it cover in 12/3 hrs?
Solution:
we know Speed = Distance/Time
180/4 = Distance/(12/3)
180/4*12/3 = Distance
Distance = 180*12/4*3
= 180 Km
6. What is the area of the rectangular park if it is 140/3m long and 50/3m broad?
Solution:
Area of rectangular park = 140/3*50/3
= 140*50/9
= 777.77m
Therefore, the area of the rectangular park is 777.77m
7. Find the area of the square plot if the side of the square measures 7/2 m?
Solution:
Area of Square Plot = S*S
= 7/2*7/2
= 49/4 Sqmt
Therefore, the Area of the Square Plot is 49/4 Sqmt.
8. One-liter diesel cost Rs. 56. How much does 35 liters of Diesel Cost?
Solution:
35 liters of Diesel = 35*56
= Rs. 1960
9. An Airplane covers 920 km in an hour. How much distance does it cover in 15/6 hours?
Solution:
1 hour = 920 km
15/6 hours = 15/6*920
= 2300Km
Therefore, the airplane covers a distance of 2300km in 15/6 hours.
10. Product of Two Rational Numbers is 42/5 and if one of them is 36/7. Find the other rational number?
Solution:
Product of Two Rational Numbers = 42/5
36/7*x= 42/5
x = (42/5)/(36/7)
= 42/5*7/36
= 42*7/5*36
= 294/180
= 49/30
The Other Rational Number is 49/30.
11. Geeta had $250 She spent 1/2 of her money on books and 1/4 of the remainder on stationery items. How much money is left with her?
Solution:
Geeta had a total money = $250
She spent 1/2 of her money on books = $250/2
= $125
Of the remaining money she spends 1/4 on Stationery Items i.e. 1/4($125)
= $ 31.25
Total money left with her = $250-( $125 – $ 31.25)
= $93.75
12. Area of a room is 214/2 m2. If the breadth is 83/4m what is its length?
Solution:
Area of a room = 214/2 m2
Breadth is 83/4 m
Length =?
Area of the Room = Length*Breadth
214/2 = 83/4*length
Length = (214/2)/(83/4)
= 214/2*4/83
= 214*4/2*83
= 856/166
= 428/83
Therefore, the Length of the Room is 428/83 m.
