Please help me guys I am begging you please guys please....​

Answer 1

Answer:

1. 9:5 = 9/5 = 90,000/x (let new weight be x)

cross multiply 9/5=90,000/x

we get 5 x 90,000 = 9x

5 x 90,000/9 = x

therefore , x = 50,000 kg

2. a:b:c = 25000:50000:75000 = 25:50:75=5:10:15 = 1:2:3 (simplified )

1x + 2x + 3x = 18000

6x = 18000

x=18000/6

x = 3,000 rupee

3. i think question is wrong or either it will the "ratio 1:1:3"

4.area of map=24×18

=432 sq.cm

area of land and water presented in map = 432×10×10

=43200sq

sum of terms in ratio=7+2=9

area of land=7/9×43200

=33600sq.km
