If % = division, $ = addition, @ = subtraction,
If % = division, $ = addition, @ = subtraction, and # = multiplication, evaluate 81 % 9 & 15 @ 7 # 2.
यदि % = भाग (÷), $ = जोड़ (+), @ = घटाना (−), और # = गुणा (×) है, तो
81 % 9 & 15 @ 7 # 2 का मान निकालिए।
Detailed Solution & Logic
Correct Answer:
10
Expression को बदलकर लिखें:
81 ÷ 9 + 15 − 7 × 2
अब step by step हल करें (BODMAS/PEMDAS नियम अनुसार):
-
Division और multiplication पहले:
81 ÷ 9 = 9
7 × 2 = 14
तो expression बन गया:
9 + 15 − 14
-
अब addition और subtraction बाएँ से दाएँ:
9 + 15 = 24
24 − 14 = 10
