Question

E) Astha wants some Hong Kong Dollars and Won.
1) How many Won can she change for Rs 4? For Rs 400?
2) How many Hong Kong Dollars can she change for Rs 508?​

Answer 1

Answer:

1) 100 Won for Rs.4 and 10000 won for Rs.400

2) 99 Hong Kong Dollar

Step-by-step explanation:

(E) (1) We find from the chart,

1 Won = Re 0.04 = 4 paise

We know that, Re 1 = 100 paiseo, Rs 4 = 4 × 100 paise = 400 paise Rs 400 = 400 × 100 paise = 40000 paise

Now,  4 paise = 1 Won So, 400 paise = 400 ÷ 4 Won = 100 Won

and 40000 paise = 40000 ​÷ 4 Won = 10000 Won

Thus, Astha can change 100 Won for Rs 4, and 10000 Won for Rs 400.

(2) We find from the chart,

1 Hong Kong Dollar = Rs 5.10 = 5 rupees 10 paise = 5 × 100 + 10 paise = 500 + 10 paise = 510 paise

Total money with Astha = Rs 508 = 508 × 100 paise = 50800 paise

50800 paise = 50490 + 310 paise

50800 paise = 510 × 99 + 310 paise

50800 paise = 510 HKD + 310 paise

Now, 310 paise = 300 paise + 10 paise = 3 rupees and 10 paise = Rs 3.10

Thus, Astha can change 99 HKD for Rs 508 and Rs 3.10 is left with her.
