=> Required ratio= (3x/4)*(4/x)= 3/1= 3:1.

It is mysterious because the sound produced by the fan seems to say something but the poet is not able to understand it. The chatter is electrical because it runs on electricity and thus, the fan doesn't talk or chatter talk on its own.

Given the ratio of the ages of two students = 5 : 3
Let their ages be 5<m:omath><m:r>x</m:r></m:omath> and 3<m:omath><m:r>x</m:r></m:omath>
After 6 years, their ages will be 5<m:omath><m:r>x</m:r></m:omath> + 6 and 3<m:omath><m:r>x</m:r></m:omath> + 6
Ratio of their ages after 6 years = 7 : 5
According to the question:
5<m:omath><m:r>x</m:r></m:omath> + 6 : 3<m:omath><m:r>x</m:r></m:omath> + 6 = 7 : 5
Product of mean = Product of extreme
⇒ 5(5<m:omath><m:r>x</m:r></m:omath> + 6) = 7 (3<m:omath><m:r>x</m:r></m:omath> + 6)
⇒ 25<m:omath><m:r>x</m:r></m:omath> + 30 = 21<m:omath><m:r>x</m:r></m:omath> + 42
⇒ 25<m:omath><m:r>x</m:r></m:omath> - 21<m:omath><m:r>x</m:r></m:omath> = 42 – 30
⇒ 4<m:omath><m:r>x</m:r></m:omath> = 8<m:omath><m:r>
⇒ x</m:r></m:omath> = 2
Hence the present ages of two students are 5(2) = 10 years and 3(2) = 6 years.

Aadarsh Kumar Singh 2 years, 11 months ago

Let the number be x Then, 13+x=37 x=37-13 x=24
Let the number be x 13+(x+x)=37 x+x=37-13 x+x=24 24÷2=12 Therefore x=12

Let the number be = x x+13=37 x=37-13 x=24 The number is 24 13+24=37

Step-by-step explanation:

37-[5+{28-(19-7)}]

=37-[5+{28-(12)}]

=37-[5+{28-12}]

=37-[5+{16}]

=37-[5+16]

=37-[21]

=37-21

=16

16
=37-[5+(28-{19-7})] =37-[5+(28-12)] =37-[5+16] =37-21 =16
