Match the average rainfall with climatic region:
(a) Less than 500 - (2) Arid (b) 500-700 - (3) Semi arid (c) 750-1000 - (1) Sub humid (d) More than 1000 - (4) Humid
139 + 323 – √169 + ? = 450
Find the value of x.
√441 ÷ 21+ √400 = 1 × x
675 ÷ 15 + 225 – 18 × 6 = ?
15(2/9) + 11(2/9) + 17(1/9) + 13(4/9) = ?
345 = √2704 ÷ (?% of 104) + 7 3
5/2 of 5/6 of 12/5 of 54 % of 5250 = ?
14% of 700 + 15% of 900 + 10% of 160 = ?
21% of 400 − 150 = ? − 77
25% of 1000 + 10% of 150 – 22 × ? = 45
2350 – 4830 + 9570 + 3350 – 1720 = ?
