Solution:

GIVEN:
Loss = 20% when SP = Rs. 2000
FORMULA USED:
Profit = [(SP - CP)/CP] × 100
Loss = [(CP - SP)/CP] × 100
CALCULATION:
Since loss is of 20% we can calculate CP as:

20 = [(CP - 2000){/}CP] × 100

⇒ CP

= 2000{/}0.8 = 2500

Now he sells the pen at Rs. 2250:
So,
Loss %

= [(2500 - 2250){/}2500] × 100

= 25000{/}2500

Loss % = 10%
