How to form at least two combination using notes for rupees 5631

Answer 1

Answer:

total of 18 ways.

There are notes of 3 denominations (50, 10 and 1).

So lets see the number of possible ways:

Scenario 1

When no 50Rs note is used:

we can have either

a. 0 tens and 107 ones, or

b. 1 ten and 97 ones

c. or 2 tens and 87 ones

... 10 tens:

so we have 11 possible ways.

Scenario 2

When 1 50 Rs note is used:

we can have either:

a. 0 tens and 57 ones

b. 1 ten and 47 ones

... 5 tens

so we get 6 possible ways

Scenario 3

Wehn we use 2 50Rs notes. then the only way is to use 7 ones for remaining amount.

Thus we have a total of 18 possible ways (11+6+1)
