?110¹/4
Multiply the denominator 4 with 100 and add the numerator 1.
= ?441 / 4
Simply the number in simple multiplication
= ?3 x 3 x 7 x 7 / 2 x 2
= 3 x 7/2 = 21/2
= 10.5

Given, ?x/169 = 18/13
On squaring both sides, we get
x/169 = 18/13 x 18/13
? x = 18 x 18 x 169/13 x 13
x = 18 x 18 = 324

Given that,
⁶?0.000729
first method to solve the equation.
after removing the decimal, the equation will be
= ⁶?729/1000000
Simplify the equation.
= ⁶?3 x 3 x 3 x 3 x 3 x 3 / 10 x 10 x 10 x 10 x 10 x 10
= ⁶?3⁶/10⁶
= ⁶?( 3/10 )⁶
After simplifying the root we will get,
= ( 3/10 )^{6 x 1/6}
= 3/10
= 0.3


Second method to solve the equation.
simplify the the number in multiplication of numbers.
⁶?0.000729
⁶?0.3 x 0.3 x 0.3 x 0.3 x 0.3 x 0.3
= ⁶?(0.3)⁶
remove the root and simplify ,
= (0.3)^{6 x 1/6}
= 0.3

Given that,
?16 + ?9.5 x 0.0085 x 18.9/0.021 x 0.0017 x 1.9
remove the decimal and simply the euqation.
= ?16 + ?95 x 85 x 18900/21 x 17 x 19
= 4 + ?5 x 5 x 900
= 4 + 5 x 30
= 4 + 150
= 154

. 000216 1 3 = 216 10 6 1 3 = 6 * 6 * 6 10 2 * 10 2 * 10 2 1 3 = 6 10 2 = 0 . 06

$$\begin{gathered} 6760000 = 0 . 00000676 × 10 2 \\ = 0 . 00000676 × 10 2 \\ = 0 . 0026 × 10 6 = 2600 \end{gathered}$$

Money collected = (59.29 x 100) paise = 5929 paise.

  Number of members =  5929 = 77.
