Question

Fill the squares with all the numbers from 46 to 54
rule:- total of each line should be 150.

		49
46
	52	47

Answer 1

$a=53$	$b=48$	$49$
$46$	$c=50$	$d=54$
$e=51$	$52$	$47$

Working:

$49+d+47=150$

$\Rightarrow d=150-49-47=54$

$46+c+d=150$

$\Rightarrow c=150-46-d=104-d=104-54=50$

$b+c+52=150$

$\Rightarrow b+50+52=150$

$\Rightarrow b=150-102=48$

$a+48+49=150$

$\Rightarrow a=150-97=53$

$53+46+e=150$

$\Rightarrow e=150-99=51$
