Question

23 * 5 = 65, 45 * 7= 287 34 *3 = 75, 50* 1= ?

Answer 1

• Given:- 23 * 5 = 65, 45 * 7= 287 34 *3 = 75

• To find:- 50* 1= ?

• Solution:- According to the series, the format is like,AB*C= {AB - (X+Y)×X}× C

and then AB*C= {AB - (X)×X}× C

then AB*C= {AB - (Y)×Y}× C

thenAB*C= {AB - (X+Y)×Y}× C

and so,

23*5={ 23- (5×2)}×5=65

45*7= {45- (2×2)}×7 = 287

34*3= {34-(3×3)}× 3 = 75

and then

50*1= {50- (5×3)}× 1= 35

So the final answer 50* 1= 35.
