= [ (-12/7) + (13/5) ] ÷ [ (-1/2) × (31/7) ]

= [ (-60+91)/35 ] ÷ [ -31/14 ]

= 31/35 ÷ -31/14

= 31/35 × -14/31

= -14/35

= -2/5

salary spent on food = 20%

salary spent on cosmetics = 10%

salary spent on donation = 3%

so, 20+10+3 =33% = 495

so, 33/100 × a = 495

a = 495 ÷ 33/100

a = 495 × 100/33

a = 45 × 100/3

a = 15 × 100

a = 1500

so salary of Ashna for this month is 1500
