Accepted Answer

To find the percentage by which E is lower than B, use the formula: [(B - E) / B] × 100. Based on the given data, the difference is 80% of B.

Question 4

What is the area (in sq cm) of an equilateral triangle of side 6 cm?

Accepted Answer

The area of an equilateral triangle is given by the formula (√3/4) × a². Substituting a = 6, we get (√3/4) × 36 = 9√3 sq cm.

Question 5

The difference between compound interest and simple interest on a sum for 2 year at 20% per annum is Rs 200. If the interest is compounded half yearly, then what is the difference (in Rs) between compound and simple interest for 1st year? 9/8/2017 Staff Selection Commision http://thepracticetest.in/cs_cglet1_17/response_questions.php?t_id=MTIwODIwMTc=&appid=1368062d74107fc05177712c90c3885c# 22/32

Accepted Answer

Difference for 2 years is P(R/100)² = 200, so P(0.2)² = 200, giving P = 5000. For 1 year half-yearly, rate is 10% and periods = 2. Difference = 5000(0.1)² = 50.

Question 6

Question 9

If (3)2 @ 1 * 7 = 98 and  (4)2 @ 2 * 16 = 178, then (5)2 @ 3 * 9 = ? (5)2 @ 3 * 9 = ?

Accepted Answer

The pattern is: (A)² concatenated with B, then add C. For (5)2 @ 3 * 9: 5² = 25, concatenated with 3 gives 253. 253 + 9 = 262.

Question 17

What is the slope of the line 2x + 3y = 12?

Accepted Answer

Convert the equation to the slope-intercept form y = mx + c. 3y = -2x + 12, which gives y = (-2/3)x + 4. Thus, the slope m is -2/3.

Question 18

After a discount of 23% an article is sold for Rs 1848. What is the marked price (in Rs) of the article?

Accepted Answer

Let the Marked Price be x. After a 23% discount, the selling price is 77% of x. So, 0.77x = 1848. Solving this gives x = 1848 / 0.77 = 2400.
