A postman has to deliver 450 letters . The number of letters delivered in one street is twice the number delivired in other . If
timofeeve [1]

Answer:

The number of letters in the one street be 220 .

Step-by-step explanation:

As given

A postman has to deliver 450 letters .

The number of letters delivered in one street is twice the number delivered in other .

Let us assume that the number of letters delivered in second street be x.

Let us assume that the number of letters delivered in first street = 2x

As given

If he is left with 120 letters .

Thus

The number of letter delivered in one and other street  = 450 - 120

                                                                                            = 330

Than the equation becomes

x + 2x = 330

3x = 330

x = \frac{330}{3}

x = 110

The number of letters in the one street = 2 × 110

                                                                  = 220

Therefore the number of letters delivered in first street be 220.
