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
