Q. $\LARGE { \frac{5}{4}}$ times a number is 10 more than the number. Find the number?
Sol. =
Covert the statement step by step into a mathematical expression.
=> Let the unknown number be, x
=> $\LARGE { \frac{5}{4}}$ times a number = $\LARGE { \frac{5}{4}\times x}$

=> 10 more than the number = $\LARGE {10 + x}$
=> Therefore, $\LARGE { \frac{5}{4}\times x}$ $\LARGE { = 10 + x}$

$\huge {=> 5\times x = 4\times (10+x)}\\ \huge{=> 5 x= 40+4x }\\ \huge{=> 5 x-4x= 40 }\\ \huge{=> x= 40 }\\$
Final answer, x = 40.

The greatest 5-digit number is 99999 and
The smallest 5-digit number is 10000.
But by using different digits,
The greatest 5-digit number is 98765 and using 4 at the tenth place we will get
=> 98746
Similarly, The smallest 5-digit number is 10234 and using 4 at the tenth place we will get
=> 10243

So, according to the conditions given in the question:
The greatest 5-digit number is 98746 and
The smallest 5-digit number is 10243, having 4 at the tenth place and with different digits.

Yogita Ingle 5 years, 4 months ago

The 1878 Forest Act, divided forests in India into three categories reserved, protected and village forests.
The consequences of this Act were :

Villagers used forests for different needs, i.e. for fuel, fodder and leaves. After Forest Act they could not take anything from the reserved forests.
In forest areas people graze their cattle, collect fruits and roots and hunt animals and fish. Almost everything was available in the forest for their livelihood. The Forest Act meant severe hardship for them. All their practices became illegal.
Circumstances forced the villagers to steal wood and if they were caught, forest guard claimed bribe from them. Women who collected fuelfood were scared of the forest guards as they harassed them and demanded free food.
After the Forest Act, the forest department only encouraged to plant Teak and Sal tree for commercial uses.

A mistake in the question, "class assado" = cast's a shadow.

Sol:

From eq. 1 and eq. 2 we will get:

$\huge {=>\ \frac{6}{y+3} = \frac{1.5}{3} }\\ \huge {=>\ 6\times3 = 1.5\times(y+3) }\\ \huge {=>\ \frac{18}{1.5} = y+3}\\ \huge {=>\ 12 = \frac{y}{3} }\\ \huge {=>\ 12-3 = y }\\ \huge {=>\ y=9 }\\$
