Answer:
hey here is your answer
pls mark it as brainliest
Step-by-step explanation:
so let the required two digit number be 10x+y
wherein digit at tens place is x and that of units place is y
so number obtained by reversing digits is
10y+x
according to the first condition
10x+y+10y+x=143
ie 11x+11y=143
so x+y=13 (1)
according to the second condition
x-y=5 (2)
adding (1) and (2)
we get
2x=18
ie x=9
substitute value of x in any of two equations
we get y=4
thus then our required two digit number=10x+y
=(10×9)+4
=90+4
=94
so thus then
94×(9+4)
=94×13
=1222
also thus then reversed digit=49
so 49×13
=637
thus option d is ryt
