Question 9

Manisha took 15 litres milk for (RBSESolutions.com) selling It out. She sold [latex]\frac { 2 }{ 5 }[/latex] part of milk to Kanchan and [latex]\frac { 1 }{ 5 }[/latex] part of milk to Bhawna and remaining part to a hotel. Find

(i) How much milk she sold to Kanchan?

(ii) How much milk she sold to Bhawna?

(ill) How much milk she sold to hotel?

Question 10

7 boys were placed each [latex]\frac { 3 }{ 4 }[/latex] meter (RBSESolutions.com) apart from the other for PT demonstration on independence day. What is the distance between the first and the last boy?

Solution:

Let 7 children A, B, C, D, E, F and G are standing

AB= BC = CD = DE = EF = FG = [latex]\frac { 3 }{ 4 }[/latex]m

∴Distance between frist and last children

= AG = 6 × AB

= 6 × [latex]\frac { 3 }{ 4 }[/latex]

= [latex]\frac { 3\times 3 }{ 2 }[/latex] = [latex]\frac { 9 }{ 2 }[/latex] m

Question 11

Rahul works on a painting 2 hours daily. If he (RBSESolutions.com) takes 8 days to complete this painting then calculate the number of hours he worked.

Solution:

Rahul ‘s one day work = 2[latex]\frac { 3 }{ 4 }[/latex] = [latex]\frac { 11 }{ 4 }[/latex]hrs

∴ Rahul’s 8 days work =[latex]\frac { 11 }{ 4 }[/latex] x 8

= 11 x 2 = 22 hrs.

Question 12

A car travel 23[latex]\frac { 1 }{ 5 }[/latex] km using 1 litre petrol. What (RBSESolutions.com) distance will it travel using 2[latex]\frac { 3 }{ 4 }[/latex] litre petrol?

Solution:

∵ Distance covered by car in I litre petrol

= 23[latex]\frac { 1 }{ 5 }[/latex] km = [latex]\frac { 116 }{ 5 }[/latex] km
