Question
The annual production of an article fluctuates. It
consistently rises by 25% for two consecutive years, followed by a 20% decline in the third year. In the fourth year, production again increases by 12%. Starting from 2008, what is the approximate overall impact on the production of the article after four years?Solution
SOLUTION: Let initially production of article was N Then, production after 4 years = N× 
= 1.4N Increased in production = 1.4N-N = 0.4N Increased percentage production = 0.4N/N ×100 = 40% Which means production of that article after 4 years will be increased by 40%.
What will come in the place of question mark (?) in the given expression?
(11/45) of 225 + 3 X 75 = ? X (72 ÷ 6 + 4)
182 – 517 ÷ 11 - √361 = ?
√11025 x √5625 - (50)² = (?) + (73)²
What is 12% of 4% of 7% of 2 x 106 ?
37% of 810 – 32% of 460.5 = ?
19 × ? =361 ÷ 19
What will come in place of the question mark (?) in the following expression?
46 – 5² + 8² + 3² = ? × 4
[(120)2 ÷24 ×25] ÷ 250 =?
Simplify the following expressions and choose the correct option.
864 ÷ 16 + 2⁵ × 3 = ?
{(522 – 482 ) ÷ (27 + 73)} × 35 = ?% of 175
