Answer  

Find out the how many notes of each denomination did she give .

To prove

Let us assume that x be the scalar multiplication of the Rs 50, Rs100,Rs500 curreny notes.

As given

Kamala gave Rs 1,50,000 to her friend.

She gave currency notes of denomination Rs. 50,Rs.100,Rs.500 in the ratio 4:3:5.

Rs50 currency note gave in the denomination = 4x

Rs100 currency note gave in the denomination = 3x

Rs500 currency note gave in the denomination = 5x

than the equation becomes

4x + 3x + 5x = 150000

12x = 150000

x = 12500

Thus

Rs50 currency note gave in the denomination = 4 × 12500

                                                                             = 50000

Rs100 currency note gave in the denomination = 3 × 12500

                                                                             = 37500

Rs500 currency note gave in the denomination = 5 × 12500

                                                                             = 62500
