Question 15.

During a festival sale, the cost of an object is ₹ 870 on which 20% is off. The same object is available at other shops for ₹ 975 with a discount of 6\(\frac { 2 }{ 3 }\) %. Which is a better deal and by how much?

Solution:

The cost of the object = ₹ 870

Discount = 20% of ₹ 870 = \(\frac { 20 }{ 100 }\) × 870 = ₹ 174

Selling price = ₹ 870 – ₹ 174 = ₹ 696

The same object is available at other shop = ₹ 975

Selling price = ₹ 975 – ₹ 65 = ₹ 910

Since ₹ 910 > ₹ 696

Hence, deal at first shop is better and by ₹ 910 – ₹ 696 = ₹ 214

Question 16.

Simplify:

21.5 ÷ 5 – \(\frac { 1 }{ 5 }\) of (20.5 – 5.5) + 0.5 × 8.5

Solution:

Using BODMAS rule, we have

21.5 ÷ 5 – \(\frac { 1 }{ 5 }\) of (20.5 – 5.5) + 0.5 × 8.5

= 21.5 ÷ 5 – \(\frac { 1 }{ 5 }\) of 15 + 0.5 × 8.5

= 21.5 × \(\frac { 1 }{ 5 }\) – \(\frac { 1 }{ 5 }\) × 15 + 0.5 × 8.5

= 4.3 – 3 + 4.25

= 4.3 + 4.25 – 3

= 8.55 – 3

= 5.55

Question 17.

Simplify:

Solution:

Using BODMAS rule, we have

2.3 – [1.89 – {3.6 – (2.7 – 0.77)}]

= 2.3 – [1.89 – {3.6 – 1.93}]

= 2.3 – [1.89 – 1.67]

= 2.3 – 0.22

= 2.08

Question 18.

Solution:

Using BODMAS rule, we have
