140x - 230y = - 511   ....(i)

-330x + 149y = -32   ......(ii)

By applying 33 x (1) + 14 x (2) , we obtain

(4620x - 7590y) + (-4620x + 2086y) = -16863 - 448

⇒ - 5504 y = -17311

⇒ \(y = \frac{17311}{5504} \approx 3.145\)

From (i), we get 

140x = 230y - 511

= 230(3.145) -511

= 212.35

⇒ \(x \approx \frac{212.35}{140}\approx 1.517\) 

Hence, x \(\approx\) 1.517 & y \(\approx\) 3.145 is solution of given system.

\(\frac5x-2y=\frac{17}3\)---(1)

\(\frac2x+3y=\frac{-16}3\)---(2), x \(\neq\) 0

By doing, 3 x (1) + 2 x (2), we obtain

\((\frac{15}x-6y) + (\frac yx+6y) = \frac{51}3-\frac{32}3\)

⇒ \(\frac{19}x=\frac{19}3\)

⇒ x = 3

∴ 5/3 - 2y = 17/3

⇒ 2y = 5/3 - 17/3 = -12/3 = -4

⇒ y = -2

Explanation:

Hardwood & Softwood trees

• The terms hardwood and softwood can be very confusing, as not all commercially classified hardwoods are physically hard, or softwoods soft.
• For example, the obeche tree is classed as a hardwood tree, yet it offers little resistance to a saw or chisel, etc.
• The yew tree, on the other hand, is much harder to work yet it is classified as a softwood.
• To add to this confusion we could be led to believe that hardwood trees are deciduous (shed their leaves at the end of their growing season) and softwood trees are evergreen (retain their leaves for more than one year), which is true of most species within these groups but not all!
• From the above, Shesham is the hardest wood.

Correct option is C) hyper

Concept used:-

Trick to find square root of a number.

Method and Calculation:-

 • Find the unit digit of square root by looking at unit digit of given number.

For ✓48841, unit digit must be 9 or 1

 • Find other two digits by looking at number formed by first 3 digit.

484 < 488 < 529 (584 and 529 are squares of 22 and 23, so remaining part  of square root will be 22.

 • Find the square root from the narrowed down options.

✓48841 = 221 or 229. To find this, we multiply 22 × 23, which is equal to 506 and is more than 488. Hence the smaller of two will be the square root

Clearly, ✓48841 = 221

The most common methods of propagation in chrysanthemum are by suckers and cuttings:

A) Suckers: After the flowering is over the plants are beheaded to a height of about 15-20 cm from the ground level. During January February, new suckers start appearing round the base of the stool and these are separated and planted in 10 cm pots. The suckers have their own root system. The pots should be kept in light shade to allow more rooting. 

B) Cuttings: After flowering is over the plants are cut to ground level as stated above. New shoots arise from the base as well as from axils of leaves. Young tip cuttings measuring 5-8 cm are taken just above a node. The lower leaves are removed and the basal portion of the cuttings are treated with some root promoting hormones like seradix before planting.
