Concept used:
Calculation:
√(√8100 + √6241) = ?
⇒ √(√8100 + √6241) = ?
⇒ √(90 + 79) = ?
⇒ √169 = ?
⇒ 13 = ?
∴ The value of ? is 13

Concept used:
Follow BODMAS rule to solve this question, as per the order given below:
Step-1: Parts of an equation enclosed in 'Brackets' must be solved first, and in the bracket,
Step-2: Any mathematical 'Of' or 'Exponent' must be solved next,
Step-3: Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated,
Step-4: Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.
Now,
Calculations:
15 × 13 + 30 = ?2
⇒ ?2 = 225
⇒ ? = 15
What value should come in the place of (x) in the following question?
25% of 48 + 20% of x = 60

Correct answer
240
Why this answer is correct
Follow BODMAS rule to solve this question, as per the order given below:
Step-1: Parts of an equation enclosed in 'Brackets' must be solved first, and in the bracket,
Step-2: Any mathematical 'Of' or 'Exponent' must be solved next,
Step-3: Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated,
Step-4: Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.
Calculations:
25% of 48 + 20% of x = 60
⇒ (25/100) × 48 + (20/100) × x = 60
⇒ 12 + x/5 = 60
⇒ x/5 = 48
⇒ x = 240.
