Let the digit at ten's place be x Since we are given that the digit in the ones place of a 2 digit number is twice the digit at the tens...

Correct option is B) Isotopes

Correct option is (A) bh Area of a parallelogram = Base \(\times\) Height = bh square units

Correct option is (C) 1 Area of flag \(=\frac12\times\) Base \(\times\) Height \(=\frac12\times(2+\sqrt2)\times(2-\sqrt2)\) \(=\frac{4-2}2\) = 1 square units

Correct option is (A) 1/10 Total two-digit number is n(S) = 99 - 9 = 90 2-digit numbers whose units & ten’s places have same digits are 11, 22, 33, 44, 55, 66, 77, 88 and...
