Answer: 96
Step-by-step explanation:
2 [3] 4 = 14 can be obtained from
⇒[ (4+3) * 2 ] * [4 - 3]
⇒[ 7 * 2 ] * 1
⇒14
Similarly, 3 [4] 6 =60 can be obtained from
⇒[ ( 6 + 4 ) * 3 ] * [ 6 - 4 ]
⇒[ 10 * 3 ] * [2]
⇒ 60
Hence we analyzed that if :
a [b] c is given it's answer can be obtained by solving
⇒ [ ( c + b) * a ] * [ c - b ]
So, the answer of 4 [5] 7 is:
⇒[ (7 + 5) * 4 ] * [ 7 - 5 ]
⇒[12 * 4] * 2
⇒ 48 * 2
⇒ 96
