Shreya2103: actually I want the whole answer

TheGENIUSBoy: ok,

TheGENIUSBoy: Let the number be 10x+y and sum of its digits is =x+y.A/Q 10x+y=7(x+y)=3x-6y=0=x-2y=0 and this is our 1st equation. Now forming 2nd equation A/Q (10x+y)-27=10y + x=9x-9y=27=x-y=3 this is our 2nd equation, Now solve these equations to find x and y
