Let $X be the original saving.1/10 X = 145
X = 145(10)
X = 1450
Therefore, the original saving is $1450.

let y to be his saving,
y*1/10=145
y=1450
because of he spent $20 on buying pens ,
so the original saving is 1450+20
=1470
y*1/10=145
y=1450
because of he spent $20 on buying pens ,
so the original saving is 1450+20
=1470

The original saving is:145/(1/10)
=145X10
=$1450
The original saving is:145/(1/10)
=145X10
=$1450
