(i) -77 + (-84) + 318

(ii) 54 + (-218) – (-76)

(iii) -121 – (-78) + (-193) + 576

Question 3.

Find the value of:

(i) 8 – 6 + (-2) – (-3) + 1

(ii) 31 + (-23) – 35 + 18 – 4 – (-3)

Solution:

(i) 8 – 6 + (-2) – (-3) + 1

= 8 – 6 – 2 + 3 + 1

=-6 – 2 + 8 + 3 + 1

= -6 – 2 + 12

=-8 + 12 = 4

(ii) 31 + (-23) – 35 + 18 – 4 – (-3)

= 31 – 23 – 35 + 18 – 4 + 3

= -23 – 35 – 4 + 31 + 18 + 3

= -23 – 35 – 4 + 52

= -62 + 52 = -10

Question 4.

Rashmi deposited ₹ 4370 in her account on Monday and then withdrew ₹ 2875 on Tuesday. Next day she deposited ₹ 1550. What was her balance on Thursday?

Solution:

Rashmi deposited in her account on Monday = ₹ 4370

Less withdrawal on Tuesday = ₹ 2875

So the Balance on Tuesday

= ₹ 4370 – ₹ 2875

= ₹ 1495

Again she deposited on Wednesday = ₹ 1550

Balance on Thursday

= ₹ 1495 + ₹ 1550 = ₹ 3045
