Question

दो अंको की संख्या का दहाई अंक,इकाई अंक का तिगुना है यदि अंक बदल दिए जाएं तो प्राप्त संख्या मूल संख्या से 36 कम हो जाती है संख्या ज्ञात करे

Answer 1

Answer:62

Step-by-step explanation:

let the number is 10x+y

as given ten's digit is 3 times of one's

then 3y=x ------------1

in second condition by interchanging digit

10x+y=10y+x+36

⇒9x-9y= 36

⇒x-y= 4

by putting value of y from equation 1

⇒3y-y= 4

⇒ 2y = 4

⇒y=2

as y= 2, put the value in eqation 1 we get x=6

so the number is 62

Answer 2

Answer:

Mana ki ikai=x

dahai=10x

to prasn se,3(10x)+x

to sankhya=31x

to sankhya ko palatne par,3x+10x=13x

to prashn se,31x-13x=36

,18x=36

x=36/18=2

to mul sankhya=31x=31×2=62
