Explanation

We're given:

1. A + B + C = 112
2. B = A - 12
3. C = 2B

We can substitute B in the first equation using the second equation:

A + (A - 12) + C = 112 2A + C - 12 = 112 2A + C = 124

Now, we can substitute C using the third equation:

2A + 2B = 124

We know B = A - 12,

so: 2A + 2(A - 12) = 124 2A + 2A - 24 = 124 4A = 148 A = 37

Now we can find B and C: B = A - 12 = 37 - 12 = 25 C = 2B = 2 * 25 = 50

Therefore, C gets $50.

Explanation

In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself

400-367=33

Explanation

425-400=25

Explanation

Formula

New price = (1+-- r) original price

Example

Aslam Paid 320Rs for a laptop after receiving 20% discount. what was the original price?

New price = (1+-- r) original price

320 = (1-.20) x

320=.80x

320/.80 = .80x/.80

=400

Explanation

Explanation

Ratio of wages of 6 men, 8 women and 6 = (6 x 4) : (8 x 3) : (6 x 2) = 24: 24 : 12

= 2 : 2 : 1

∴ Total money earned by children = Rs. (950 x 1/5)

= Rs. 190

total money earned by children=12*95/6 =190

Explanation

Here we have to find the Sum of First 70 even Numbers

First 70 even Numbers are

2 , 4 , 6 , 8 , ... , 140

This is an arithmetic progression

First term = 2

Last term = 140

Number of terms = 70

Hence the required sum

4970

Explanation

• A. √16 = 4 → Rational

• B. √4 = 2 → Rational

• C. √9 = 3 → Rational

• D. √11 ≈ 3.316624... → Not a perfect square → Irrational

Correct answer: D. √11
