Answer:
A)5336
Step-by-step explanation:
In this question,the number in the triangle is the difference of cubes.
In the first one,
90=5^3 - (3^3+2^3)
90=125-(27+8)
90=125-35
90=90
Similarly in 2nd triangle
55=10^3 - (9^3+6^3)
55=1000-(729+216)
55=1000-945
55=55
So,in the 3rd triangle,
?=21^3 - (12^3+13^3)
?= 9261- (1728+2197)
?=9261-3925
?=5336
