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.how many notes of each denomination did she give?

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

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
