Answer:

₹ 4000

Step-by-step explanation:

Sarah's salary =₹ 30000

one-tenth of her salary to an orphanage= 1/10*₹ 30000= ₹ 3000
one-third of her salary is spent on food= 1/3*₹ 30000= ₹ 10000
one-fourth of salary on rent and electricity =1/4*₹ 30000= ₹ 7500
one-twentieth of her salary on the telephone= 1/12*₹ 30000= ₹ 2500
donated some amount to the Prime Minister's relief fund = x
She was left with ₹ 3000.

x= ₹ 30000- (₹ 3000+₹ 10000+₹ 7500+₹ 2500+₹ 3000)= ₹ 4000
