Detailed Solution


Given: 95 × 96
Let us now split 95 and 96:
95 × 96 = (100 - 5 ) (100 - 4)
We shall use identity here,
(x + a) (x + b) = x² + (a + b) x + ab:
95×96=(100−5)(100−4)  
= 100 2 +[(−5)−(4)]100+(−5)(−4)  
=10000+(−9)100+20    =10000−900+20  
=10020−900  
=9120  
Hence, 95 × 96 = 9120.
Therefore, the correct option is 1.
