Verify mobile number to view the solution
: 42% of 350 + 28% of 140 = 40% 0f 350 + 2 x (1% of 350) + 25% of 140 + 3 x (1% of 140) = 147 + 39.2 = 186.2
997 x 1003 = ?
997 x 1003 = (1000 + 3)(1000 - 3) = 10002 - 32 = 999991
47489 + 94848 -? = 53638
? = 47489 + 94848 - 53638 = 88,699
648 ÷ 81 × 596 ÷ 16 = ?
? = 648 ÷ 81 × 596 ÷ 16 648/8 = 81 => ? = 596/2 = 298
25% of ? = 33.33% of 72 + 16.67% of 48
33.33% of 72 + 16.67% of 48 = 24 + 8 = 32 Thus, ? = 32/.25 = 128
What value should come in place of the question mark (?) in the following questions?
537 + 352 - 477 = ? + 217
The value in the place of ? = 537 + 352 - 477 - 217 = 195
The given expression = 47+39 = 86
70% of 5450 - 30% of 3150 = ?
70% of 5450 = 3815 30% of 3150 = 945 Thus the given expression = 3815-945 = 2870
3/7 of 5/9 of 2/7 of 3087 = ?
The given expression
63/? = ?/28
