Question

2[3]4=14 and 3[4]6=60 then 4[5]7=?

Answer 1

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
