What approximate value should come in place of question mark in the following equations.
1. 816.23/34.98 × 24.999 = ?
2.(4722+3272+5324)/(491+769+132)=?
3.22 1/3 % of 435.1 - 11/7 % of 1734.68 = ?
4.(1681)^1/2 + (4094)^1/3 = ?
5.(803.63)² = ?
6.(1.2)² / 1.3333 = (1.1)^? / (1.22)³
7. 2809/27.86 × 6.26 - 125.88 - 246.18 = ?
8.(13.67)² - (4.77)²+ (8.26)³ - (5.23)³ = ?
9.21% of 234.20 + 54% of 150 - 3.76% of 102.05 = ?
10.(1218)^2 / 18 = ? × 1224
Solutions and Answers :
==> (816/35)×25 = 23×25 = 575
Nearest value in options is 580
==> 13316/1392 = 13400/1400 = 9.5
Nearest value in options is 10
==> 97-27 = 70
Nearest value in options is 69
==> 41 + 16 = 57
==> (804)^2 = 646414
Nearest value in options is 646400
==> (1.1)^2 / (1.1)³= (1.1)^? / (1.21)³
==>(1/(1.1)) = (1.1)^? / (1.1)^6
==> 2809 / 28 × 6.25 - 126 - 246 = 625-372 = 253
Nearest value in options 254
==> 188-23+572-144=760-167=593
Nearest value in options is 600
==> 49+81-8 = 122
==> (1218)^2 / 18 = ? ×1224 = 67.33 = 67
