The paper presents an adaptation of Interval valued intuitionistic fuzzy number. The arithmetic operation of interval-valued intuitionistic fuzzy number (IVIFN) is addressed here. The differentiability of IVIFN valued function is also addressed here. Demonstration of intuitionistic fuzzy solutions of differential equation is carried out with the said numbers. Additionally, a illustrative application is also undertaken with the useful graph for usefulness for attained to the proposed approaches.
