This is a problem based on A.P.
Sn=n/2(2a+(n-1)d)
Where n- number of months

Sn=n/2(2a+(n-1)d)
Where n- number of months
Initial amount
d- Regular difference
91200 =24/2(2a+(23)200)
24a=36000;a=1500
Value by 15th month S15=a+(n-1)d=1500+14(200)=4300

another wrong question... If the value is 91200 after 12 months then how can it be less than 91200 in 15 months? no option is more than 91200. so none of the above..
