here,given:

a= 18000

d= 10000

an= 25000

to find: "n"

using formula: an = a + (n-1)d

⇒25000= 18000+(n-1)10000

⇒25000=18000+10000n-10000

⇒25000=8000+10000n

⇒25000-8000=10000n

⇒17000=10000n

⇒17000÷10000=n

⇒17÷10=n

⇒1.7=n

in 1.7 years sheik's salary will be rs.25000


anupamraj2003: please dont consider this answer i have done some mistake in calculation
anupamraj2003: in the last four steps there will be 7 instead of 17
anupamraj2003: and the final answer will be n= 0.7.
anupamraj2003: hence in 0.7 years sheik's salary will be 25000rs.
