Question (4) :- The Product or two numbers is (5/14). if ONE the numbers is (5/6). Find the other NUMBER ?

Solution :-

→ Let The other number = x .

Than,

A/q,

→ x * (5/6) = (5/14)

→ x = (5/14) ÷ (5/6)

→ x = (5/14) * (6/5)

→ x = (6/14)

→ x = (3/7) (ANS).

________________________

Question (5) :- By what Number should (7/15) be divided to OBTAIN (2/9) ?

Solution :-

→ Let the Number divided by x .

Than,

A/q,

→ (7/15) ÷ x = (2/9)

→ x = (7/15) ÷ (2/9)

One of the two digits of a two digit number is three times the other digit. If you interchange the digits of this two-digit number and add the resulting number to the original number, you get 88. What is the original number?Plz ans this question fast with proper explanation

SOLUTION :

$\bf{\orange{\underline{\underline{\bf{Given\::}}}}}$

ONE of the TWO digits of a two digit number is three TIMES the other digit. If you interchange the digits of the two - digit number and add the resulting number to the original number, you get 88.

$\bf{\orange{\underline{\underline{\bf{To\:find\::}}}}}$

The original number.

$\bf{\orange{\underline{\underline{\bf{Explanation\::}}}}}$

Let the one's place be r

Let the ten's place be 3r

$\bf{\underline{\sf{The\:Original\:number\:=10(3r)+r}}}}\\\bf{\underline{\sf{The\:Reversed\:number\:=10(r)+3r}}}}$

A/q

$\mapsto\sf{10(3r)+r+10r+3r=88}\\\\\mapsto\sf{30r+r+13r=88}\\\\\mapsto\sf{44r=88}\\\\\mapsto\sf{r=\cancel{\dfrac{88}{44} }}\\\\\mapsto\sf{\red{r=2}}$

Thus;

$\sf{The\:original\:number=10(3r)+r}\\\\\sf{The\:original\:number=10(3*2)+2}\\\\\sf{The\:original\:number=10(6)+2}\\\\\sf{The\:original\:number=60+2=\red{62}}$

Answer»

Step-by-step explanation:

we know that RISK and clue are PARALLELOGRAM

according to its property we know that the opposite angles are equal and adjacent angles are SUPPLEMENTARY.

here ANGLE I is 120 degrees

and the opposite angle is 60

And in the other parallelogram

angle u is 70

so the ans is 180-(70+60)

=50
