Correct Answer: $2\frac{2}{5}$

Solution : Given:
$0.3 + 0.6 + 0.7 + 0.8 = x$
$⇒x = 2.4 = \frac{24}{10} = \frac{12}{5}= 2\frac{2}{5}$
Hence, the correct answer is $2\frac{2}{5}$.

Correct Answer: April 1, 2010

Correct Answer: 10.8

Solution : LCM of 1.2 and 2.7 = LCM of $\frac{12}{10}$ and $\frac{27}{10}$
We know LCM of fractions = $\frac{\text{LCM of numerators}}{\text{HCF of denominators}}$
Now, HCF of denominators = HCF of 10 and 10 = 10
And LCM of numerators = LCM of 12 and 27 = LCM of 2² × 3 and 3³ = 108
So, LCM of 1.2 and 2.7 = $\frac{108}{10}$ = 10.8
Hence, the correct answer is 10.8.

Correct Answer: Key

Correct Answer: 85

Solution : Given:
40, 53, 68, ?, 104,125, 148

Add consecutive odd numbers starting from 13 in increasing order, to get the missing number in the series –
40 + 13 = 53; 53 + 15 = 68; 68 + 17 = 85; 85 + 19 = 104; 104 + 21 = 125; 125 + 23 = 148

So, 85 is the required missing number in the series. Hence, the first option is correct.

Correct Answer: Both assertion and reason are true, and the reason is the correct explanation of the assertion.
   

Solution : The correct answer is (a) Both assertion and reason are true, and the reason is the correct explanation of the assertion.

The assertion is true. ADRs are financial instruments issued by a depositary bank representing shares of a foreign company. These ADRs can be traded and raise funds in international markets, allowing foreign companies to access a broader investor base.

The reason is true and is the correct explanation of the assertion. ADRs are indeed issued by depositary banks in the United States and represent shares of foreign companies.

Controlling also plays a crucial role in providing feedback to employees, assessing their performance, and guiding them towards improvement. It involves comparing actual performance against the established standards or benchmarks and taking appropriate measures to address any gaps or issues.

Correct Answer: 26 cm

Solution : Given,
Perimeter of a rectangle = 68 cm
Area of the rectangle = 240 cm²
Let the length be l and breadth be b.
Perimeter of Rectangle = 2(l + b)
⇒ 2(l + b) = 68
⇒ l + b = 34............(1)
Also, Area of rectangle = l × b
⇒ l × b = 240.............(2)
From (1), we get l = 34 – b,
⇒ (34 – b) × b = 240
⇒ b² – 34b + 240 = 0
⇒ b² – 10b – 24b + 240 = 0
⇒ b(b – 10) – 24(b – 10) = 0
⇒ (b – 24)(b – 10) = 0
⇒ b = 10 or 24
$\therefore$ Length, l = 24 or 10 cm
We know, Pythagoras's theorem: Perpendicular² = Length² + Breadth²
⇒ Length of diagonal = $\sqrt{24^2+10^2}=\sqrt{576+100}=\sqrt{676}= 26\ \text{cm}$
Hence, the correct answer is 26 cm.
