Amphibia are known for living in both aquatic and
terrestrial environments during their life cycle. Where do the alimentary canal, urinary tract, and reproductive tract open in amphibians?Solution
In amphibians, these tracts open into a common chamber called the cloaca.
12 × 19 + 13 × 15 + 152 = ?% of 500
(165 × 12) ÷ 45 + 110 = ? × 2
The value of 15 × 14 – 30 + (32 + 17) is:
? = 0.05% of 12000 + 175% of 4800 – 133Â
Find the value of 27 ÷ 2 of 16 of [6 ÷ 8 of (6 ÷ 2 + 5)] + (10 ÷ 2.5 + 1)
(25 + 12) x 6 + 34 = ? + 18
65% of 102 + 14 = ? – 20
Find the value of the expression:
18 + 12 – 4 × [22 + 6 – 2 × (38 – 23)]Solve the following:
1500 ÷ (9 × 18 ÷ 6 × 3 – 45) ²
52% of 36% of 810 = 72% of 18% of ?Â
