Answer 1

Answer:

1. 350 and 490       2.650

Step-by-step explanation:

1. given Rs.840

find the parts by adding = 5+7 = 12

now, for x

x =840/12 = 70 (first part)

first ratio = 5x = 5×70 = 350

second ratio = 7x = 7×70 = 490

2. given first ratio = 250

 which means in 5:8

                      5x = 250

 so,                   x = 250/5

                         x = 50

now we have the x, so as per the formula

let the total money be 'n'.

total number of parts = 5 + 8 = 13

n / total no. of parts = x

n / 13 = 50

n = 50 × 13

n = 650
