Given:in a 2-digit number , ten’s digit is twice the unit digit

To find:if the sum of the digits is 6 find the number .

STEP BY STEP EXPLANATION:Refer to the attachment

the Number is 42

Hence verified !1Sᴏʟᴜᴛɪᴏɴ:-Let us Assume That, Required two digit number is, where ,

(10x+y)→ Ten’s digit = x

→ unit digit = y .

Now,So,→→ x = 2y ————–

Eqn.(1)And,6.So,→————– Eqn.(2)PuttingEqn(1)valueinEqn.(2),weget,→→ 3y = 6

→ y = (6/3)

→

y=2.PuttingThisvalueinEqn.(1)Now,→→ x = 2*2

→

x = 4.Therefore,→42(Ans.)Hence,TheNumberis42.
