1. Suppose, there are 5 rupees in your pocket.

• I am giving you 17 Rs. How many rupees do you have now?

• Now I am giving you 39 Rs. How many rupees do you have now?

• Now I am taking 23 Rs. back. How many rupees do you have now?

• Again I am giving you 932 Rs. How many rupees do you have now?

Solution

a=5
a=a+17              # I am giving you 17 Rs.
print(a)            # How many rupees do you have now?

a=a+39      # I am giving you 39 Rs.
print(a)    # How many rupees do you have now?

a=a-23      # I am taking 23 Rs. back.
print(a)    # How many rupees do you have now?

a=a+932     # I am giving you 932 Rs.
print(a)    # How many rupees do you have now?

1. Suppose, you have 150 rupees.

• You spend 45 rupees on a meal. How many rupees do you have now?

• Then, you spend 32 rupees on a movie ticket. How many rupees do you have now?

• Next, you spend 18 rupees on snacks. How many rupees do you have now?

• Finally, you spend 25 rupees on transportation. How many rupees do you have now?

Solution

# Initial amount
rupees = 150

# Spending amounts
rupees -= 45  # spend on meal
print(rupees)
rupees -= 32  # spend on movie ticket
print(rupees)
rupees -= 18  # spend on snacks
print(rupees)
rupees -= 25  # spend on transportation


# Final amount
print(rupees)

1. You have 200 rupees.

• You decide to buy a book for 60 rupees. How much do you have left?

• Then, you receive 30 rupees from a friend. How much do you have now?

• You decide to donate 10% of your current money to charity. How much do you have left?

• You find 5 rupees in your pocket. Add this to your current amount.

• You want to split the remaining amount equally between yourself and a friend. How much does each of you get?

• You win a prize and the amount you have is tripled. How much do you have now?

• Finally, you purchase a rose, usually the price of rose is 50 rupees but todaythe price is incremented by 10 rupees due to demand. How much do you pay now?

Solution

# Initial amount
amount = 200

# Step 1: You buy a book for 60 rupees
amount -= 60
print('Money left:',amount)

# Step 2: You receive 30 rupees from a friend
amount += 30
print('Money left:',amount)

# Step 3: You donate 10% of your current money to charity
charity_amount= amount * 10/100
amount -=charity_amount
print('Money left:',amount)

# Step 4: You find 5 rupees in your pocket
amount += 5
print('Money left:',amount)

# Step 5: You split the remaining amount equally with a friend
amount /= 2
print('Money left:',amount)

# Step 6: Your amount is tripled as you win a prize
amount *= 3
print('Money left:',amount)

# step 7: price of rose is 50 but increased by 10 rupees.

rose_price=50
rose_price+=10
print('rose price paid:',rose_price)
amount-= rose_price
print('Money left:',amount)
