According to question; (a + b + 2c) = 130 × 2 = 260……………..(1) (a + 2b + c) = 142 × 2 = 284……………..(2) (2a + b + c) = 154 × 2 = 308……………..(3) From equation (1), (2) and (3) 4 × (a + b + c) = 852 a + b + c = 213 (a + b + c)/3 = 71
What will come in the place of question mark (?) in the given expression?
45% of (√6400 × 5) = ? + 111
50% of (22 x 15) + 205 = ?
(560 ÷ 32) × (720 ÷ 48) = ?
1780 – 60 ÷ 4 x 80 = ?
The value of (40 + 3/4 of 32) /[37 + 3/4 of (34-6)] is:
Find the simplified value of the following expression:
[{12 + (13 × 4 ÷ 2 ÷ 2) × 5 – 8} + 13 of 8]
(√ 121 x 41) + (3√343 x √289 ) = ? x 19
62 + 43 + 625(1/4) - ? = 102
