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 m^{2}. If the breadth is 83/4m what is its length?

**Solution:**

Area of a room = 214/2 m^{2}

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.
