- Calculate the approximate value of the question mark (?) in the given questions:
149.88% of 19.89 + √360.81 × 3.98 = ? – 139.89246256305315None of theseOption A
30 + 19*4 =x – 140
30 + 7+ = x – 140
x = 246 - ? + 1349.79 ÷ 4.99 – 124.89 = 120.10% of 1649.98
1765183521351555None of theseOption B
x+ 1350/5 – 125 = 120/100 * 1650
x + 270 – 125 = 1980
x + 145 = 1980
x = 1835 - (?)² + 180.44 × 4.8 + 64.9 × 3.9 = 2384.88
55453540None of theseOption C
x^2 + 180 * 5 + 65 * 4 = 2385
x^2 + 900 + 260 = 2385
x= 1225 - ?% of 299.98 = (21.09)² + (18.97)² + (6.15)^3 + 2.22
305295335340350Option D
x/100 * 300 = 441 + 361 + 216 + 2
x/100 * 300= 1020
3 x = 1020
x = 340 - ?^3 × 19.98 + 15.05 % of 450.03 = (14.02)^2 + 5^√31.99
13249Option C
x^3 * 20 + 15/100 * 450 = 196 + 2
x^3 *20 + 67.5 = 198
x^3 *20 =130.5
x^3= 6.525
x=1.86 = 2 - 1575.23 / 45.09 + 25.05 * √255.85 = ?
435440395405515Option A
1575 / 45 + 25 * 16
35 + 25 * 16
35 + 400 = 435 - 25 + 3.9 × 9.9 + 9.98 = ?
65755545None of theseOption B
25 + 4 * 10 + 10 = ?
25 + 40 + 10 = ?
x = 75 - (350 × 9.99) ÷ 5.4001 + 1245.20 = ?
18052455200521051945Option E
(350 * 10) /5 + 1245 = ?
3500/5 + 1245 =?
x = 1945 - 30.95² – 10.05² + (1987.29 + 24.85 ÷ ?) = 900
12347Option A
31^2 – 10^2 + (1987 + 25 / X) = 900
961 – 100 + (2012 /x) =900
861 x +2012 = 900
x = 1.29 = 1 - 140% of 3780 + 38.78% of 140 = ?
50015187548753555347Option E
140/100 * 3780 + 39/100 * 140 = x
5292 + 54.6 = x
5347 = x
