(Eastward) Astha wants some Hong Kong Dollars and Won.

one. How many Won can she modify for Rs iv? For Rs 400?

2. How many Hong Kong Dollars tin she alter for Rs 508?

Answer-

i. We know that 1 won = Re 0.04

Past multiplying both sides by 100,

100 won = 4

Therefore, Astha gets 100 won for Rs 4.

Then, for Rs 400, she gets

100 × 100 = 10000 Won

2. We know that i HK Dollar = Rs 5.10

It can exist written every bit

= 5 rupees 10 paise

= v × 100 + ten paise

= 500 + 10

= 510 paise

Then, the total money with Astha = Rs 508

We can write it as

= 508 × 100

= 50800 paise

Here,

50800 paise = 50490 + 310 paise

Past farther calculation,

= 510 × 99 + 310 paise

= 510 HKD + 310 paise

We get

310 paise = 300 paise + 10 paise

= iii rupees 10 paise

= Rs 3. 10

Therefore, Astha tin can modify 99 HK Dollars for Rs 508, and Rs 3.ten is left with her.
