Ruchika’s monthly income = Rs 32000
Ravina’s monthly income = 32000 x (1 + $\frac{15}{100}$) = 32000 x $\frac{115}{100}$ = Rs. 36800
Ramola’s monthly income = 3 x 36800 = 110400
Ramola’s annual income = 12 x 110400 = 1324800

Total employees = 4800
45% of employees are males = $\frac{45}{100}$ x 4800 = 2160
60% of 2160 are equal to or older than 25
So 40% of 2160 are younger than 25 years = $\frac{40}{100}$ x 2160 = 864

Return speed = $\frac{40}{100}$ x 150 = 60 kmph
Average speed = $\frac{2 \times 40 \times 60}{(40 + 60)}$
$\frac{4800}{100}$ = 48kmph

Required ratio = (40-34)/(34-30)=6/4=3/2

Let the original price be Rs. 100.
New final price = 95% of (110% of Rs. 100) = Rs. 95/100×110/100×100 = Rs. 104.5
∴ Increase in price = 4.5%

Let the numbers be a,b,c,d and e.

Now $\frac{a+b+c+d+e}{5}$=57.8*5

a+b+c+d+e=292

Now, $\frac{a+b}{2}$=77.5, a+b=155

Also, $\frac{d+e}{2}$=46, d+e=92.

Now, c=292-(a+b)-(d+e)=292-92-155=42.

Hence, the correct option is C.

The number equals 8 times 17.25 = 138

Hence, 73% of the number equals 0.73*138 = 100.74

Let the numbers be a,b,c,d,e.

Hence (a+b+c+d+e)/5=49

(a+b)/2=48, a+b=96.

(d+e)/2=28,d+e=56

c=245-96-56=93

Let the numbers be a,b,c,d,e.

Hence (a+b+c+d+e)/5=49
(a+b)/2=48, a+b=96.
(d+e)/2=28,d+e=56
c=245-96-56=93
