Question 1
Mahaveer bought 5 bags of sugar for ₹16000. He (RBSESolutions.com) spent ₹200 for taxi fare, ₹120 for labour charges and ₹200 for transporttation charges. Find the selling price of per kg of sugar so as to earn a profit of ₹3 on each kg.
Solution:
Cost of 5 bags of sugar = ₹16000
Other expenses = ₹200 + ₹120 + ₹200
= ₹520
∴ Total C.P. of 5 bags of sugar
= ₹16000 + ₹520 = ₹16520
∵ Profit on 1 kg = ₹3
Profit on 5 bags or 500 kg sugar
= 500 x 3 = ₹1500
So, Profit = S.P – C.P
or S.P = C.P + Profit
= 16520+ 1500 = ₹18020
So, S.P. of 5 bags = ₹18020
S.P. of 1 bag = \(\frac { 1820 }{ 5 }\) = ₹3604

Question 2
Manoj bought a second hand car for ₹1,50,000. He spent ₹60,000 on Its (RBSESolutions.com) engine repair and ₹15000 on replacing the tyre tubes. Manoj sold this car to Jitendra for ₹2,10,000 Calculate loss or gain in this business.
Solution:
Cost of car = ₹1,50,000
Expense on engine = ₹60,000
Expense on tyre & tube = ₹15,000
Total cost price = ₹2,25,000
Selling price = ₹2,10,000
Manoj has a loss
So, Loss = C.P – S.P
= 2,25,000 – 2,10,000
Loss = ₹15,000
Manoj has a loss of ₹ 15,000

Now to represent \(\frac { 3 }{ 5 }\) on number line, the distance between 0 and S is divided in 5 equal parts and take three parts from it to mark point P. This way point P represents point \(\frac { 3 }{ 5 }\) .

(ii) We know (RBSESolutions.com) that \(\frac { 7 }{ 8 }\) is greater than 0 and less than 1.
∴ \(\frac { 7 }{ 8 }\) will be in between 0 and 1.
Now to represent \(\frac { 7 }{ 8 }\) on number line, distance between 0 and 1 is divided in 8 equal parts and take 7 parts from it to mark point P. Thus point P represent point \(\frac { 7 }{ 8 }\).

(iii) We know that \(\frac { -8 }{ 3 }\) or -2\(\frac { 2 }{ 3 }\), is greater than -3 and less than – 2 so \(\frac { -8 }{ 3 }\), will be in between -2 and – 3.
Now on number line, the (RBSESolutions.com) distance between – 2 and – 3 divided in 3 equal parts and take 2 parts from it to mark point P. This way point P represents point \(\frac { -8 }{ 3 }\).

(iv) We know that -2\(\frac { 1 }{ 2 }\) or \(\frac { -5 }{ 2 }\), is greater from – 3 and less than – 2 so \(\frac { -5 }{ 2 }\) will be in between – 2 and -3.
Now to represent \(\frac { -5 }{ 2 }\) on number line, the distance between -2 and -3 is divided in 2 equal parts and take one part from it to mark point P.
This way point P represent (RBSESolutions.com) the point –\(\frac { 5 }{ 2 }\) ( -2\(\frac { 1 }{ 2 }\)) or number line.

(v) We know that \(\frac { 5 }{ 7 }\) is greater than 0 and less than 1.
\(\frac { 5 }{ 7 }\), will be in between 1 and 1.
Now to represent \(\frac { 5 }{ 7 }\) on number line, the distance between 0 and 1 is divided in 7 equal parts and take 5 parts to make point P. This way point P

represents \(\frac { 5 }{ 7 }\) on number line.
